We propose the synthesis of biologically relevant hexahydro-1H-pyrano[3,4-c]chromenes, via a tandem Prins/Friedels-Crafts process, catalyzed by BF3.Et2O, starting from (E)- and (Z)-5-phenoxypent-3-en-1-ol. The diastereoselectivity of the process is controlled by the geometry of the homoallylic alcohol. We also point out that the Prins product can be obtained in high yields and good diastereoselectivity when the reaction is promoted by AlCl3 as Lewis acid in the presence of an external nucleophile.

The oxidative cross-coupling of phenols (3 equiv) to various substituted phenyl N,N-diethylcarbamates was explored with a variety of substrates. Pd(OAc)(2) was employed as the catalyst (20 mol%) and K2S2O8 as the stoichiometric oxidant in trifluoroacetic acid as the solvent (50 degrees C, 2 h). Carbamates without or with a substituent on the phenyl ring (Me, Ph, Cl, OMe) underwent the reaction unless the phenyl substituent was too strongly electron withdrawing (CN). Cross-coupling occurred exclusively in theorthoposition relative to the carbamate group. The regioselectivity at the phenol (orthoorparato hydroxy) was mainly determined by steric factors. Yields up to 60-70% were achieved for specific carbamate/phenol combinations.

Fangping green tea (FPGT) produced by Zhonghuang 1 (C. sinensis var. sinensis cv. Zhonghuang 1), a new tea variety, has a classical cooked corn-like aroma, which is completely different from the green tea aroma. In order to illustrate the aroma characteristics of the green tea, the volatiles of FPGT was analyzed with gas chromatography-mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O). The results showed that odor activity value (OAV) of dimethyl sulfide (DMS) was 1195.21 and the odor intensity about DMS was 6.2 in FPGT. Aroma recombination experiment also confirmed the important contribution of DMS to cooked corn-like aroma. Aroma character impact (ACI) values of DMS in tea processed by Zhonghuang 1 and Fudingdabai were 72.01% and 37.86%, respectively. This indicated that the high proportion of DMS was the dominant character of green tea with cooked corn-like aroma. In addition, the S-methylmethionine (SMM) content in fresh leaves of Zhonghuang 1 (0.21 mg/g) was significantly higher than that of Fudingdabai (0.16 mg/g), which was an important reason for high DMS content.

A series of twenty-six analogs of benzimidazole based oxadiazole have been synthesized and evaluated against alpha-glycosidase enzyme. Most the analogs showed excellent to good inhibitory potential. Among the screened analogs, analog 1, 2, 3 and 14 with IC50 values 4.6 +/- 0.1, 9.50 +/- 0.3, 2.6 +/- 0.1 and 9.30 +/- 0.4 mu M respectively showedexcellent inhibitory potential than reference drug acarbose (IC50 = 38.45 +/- 0.80 mu M). Some of the analogs like 19, 21, 22 and 23 with methyl and methoxy substituent on phenyl ring show hydrophobic interaction and were found with no inhibitory potential. The binding interactions between synthesized analogs and ligands protein were confirmed through molecular docking study. Various spectroscopic techniques like H-1 NMR, C-13 NMR, and EI-MS were used for characterization of all synthesized analogs. These derivatives were synthesized by simple mode of synthesis like heterocyclic ring formation.

The contamination of food with Aspergillus flavus has caused serious economic losses and posed a great threat to human and animal health. Cumin, a condiment and flavoring in many dishes, was showed to have great potential to prevent A. flavus contamination in the present study. By using cumin essential oil (CEO), the occurrence of A. flavus contamination on peanuts was prevented during the storage period even up to 9 months. We further identified cuminaldehyde as the predominant component in CEO with great inhibitory activity to both the growth of A. flavus and aflatoxin B1 (AFB1) biosynthesis. The data showed that the minimum inhibitory concentration (MIC) of cuminaldehyde to conidial growth was 0.64 ?L/mL, and the mycelia exposed to 0.80 ?L/mL cuminaldehyde reduced AFB1 production by more than 99% in comparison to the control. RNA-Seq profiles showed that some genes, involving the synthesis pathway of ergosterol and AFB1, were significantly downregulated in the transcription by cuminaldehyde. Further investigation confirmed a significantly reduced cellular ergosterol content in the presence of cuminaldehyde, and the qRT-RCR results were also in agreement with that by RNA-Seq, indicating down-regulated expressions of those genes involving ergosterol and AFB1 synthesis. Taken together, our study strongly supported cuminaldehyde as a potential agent for the prevention of A. flavus contamination.

The development of carbonaceous materials as metal-free catalysts integrating different types of catalysis in a single system represents a significant advance in cascade/tandem organic synthesis. Zero-dimensional carbon dots with tuneable optical properties and easily modifiable surface functionalities can be harnessed as a carbocatalyst for merging photooxidation and acid-catalyzed reactions in one pot. Herein, we explore carbon dots decorated with hydrogen sulfate groups as a photocatalyst for the dehydrogenative cross-coupling of xanthenes with ketones, arenes and 1,3-dicarbonyl compounds that showed high efficiency and selectivity under visible-light irradiation. The sulphated carbon dots demonstrate dual catalytic properties, wherein they induced the rapid photooxidation of xanthenes in the presence of molecular oxygen to form a hydroperoxy intermediate followed by coupling of nucleophiles catalysed by the acidic surface functional groups. The methodology represents an operationally simple pathway for the generation of C-C coupling products in a short reaction time with wide substrate scopes under mild conditions. The catalyst is easily separable and can be reused over multiple cycles with good efficiency.

Benzyl alcohol and a set ofpara-substituted derivatives (-NO2, -Cl, -CH3, -OCH3 and -OH) were converted to the corresponding aldehydes in a commercial continuous-flow microfluidic reactor. Due to the dimension and the rigidity of the commercial microfluidic reactor channels, a stable suspension with few-layer graphitic carbon nitride nanoparticles (GCN-TS) was used to avoid the blockage of the photocatalyst in the channels of the reactor. Preliminary photocatalytic batch experiments revealed that different reaction yields were obtained depending on the aromatic ring activating/deactivating nature of the substituent groups. Regarding the ex-periments under continuous-flow, the highest aldehyde production was obtained for the reactions with 4-methoxybenzyl alcohol as starting molecule, corresponding to 0.19 mM at a retention time of merely 0.75 min. The results show the possibility of employing microfluidic reactors for the selective photocatalytic conversion of aromatic alcohols for both process intensification and screening applications due to the drastic decrease of reaction time.

The isomalabaricanes comprise a large family of marine triterpenoids with fascinating structures that have been shown to be selective and potent apoptosis inducers in certain cancer cell lines. In this article, we describe the successful total syntheses of the isomalabaricanes stelletin A, stelletin E, and rhabdastrellic acid A, as well as the development of a general strategy to access other natural products within this unique family. High-throughput experimentation and computational chemistry methods were used in this endeavor. A preliminary structure-activity relationship study of stelletin A revealed the trans-syn-trans core motif of the isomalabaricanes to be critical for their cytotoxic activity.

ZnO thin films were deposited onto glass substrate for various deposition cycles by successive ionic layer adsorption and reaction method. Structural studies were confirmed that the films are polycrystalline with hexagonal wurtzite structure. SEM studies revealed the surface had closely packed spherical particles with pores. The transmission range was found to be above 75% and the band gap was calculated for all samples using optical studies. The changes in the oxidation state of ZnO thin film was studied using X-ray photoelectron spectroscopy. The chemical compositions of ZnO were confirmed by FTIR spectrum. The improved crystalline of ZnO thin film (50 cycles) has been chosen for the fabrication of ammonia vapour sensor. The vapour sensing behaviour of the film was observed for various concentrations of ammonia at an optimized operating temperature of 200 degrees C. The lowest detection limit was found to be 1 ppm of ammonia vapour concentration.
