A new and straightforward synthesis of the C-1-C-7 core fragment of nhatrangin A was achieved in 14 steps from achiral 3-hydroxybenzaldehyde, without the need of chiral reagents or enzymatic resolution to introduce the chiral centers. The key asymmetric steps include in particular a highly enantioselective organocatalyzed Michael addition on an aryl vinyl ketone, a Sharpless asymmetric epoxidation and a subsequent regioselective ring opening of the resulting chiral epoxide. This work represents the first formal enantioselective synthesis of nhatrangin A.

Volatile content during postharvest is a critical factor affecting the quality of rose products. However, changes in the volatile content of cut rose flowers during vase life have not yet been identified although the maturity of flower petals may result in the significant changes of volatile profiles. The present study investigated volatile changes in the petals of two rose varieties, ‘Fuego’ exhibited to longer vase life and ‘Red eagle, during vase life. ‘Fuego’ petals contained 31 volatiles, of which 12 increased and 11 decreased in content during vase life. ‘Red Eagle’ petals contained 37 volatiles, of which 9 increased and 19 decreased. The major components that increased during vase life included 2-ethylhexan-1-ol and phenylmethanol in ‘Fuego’ and hexan-1-ol and 2-phenylacetaldehyde in both cultivars, whereas the major components that decreased during vase life included methyl butanoate in ‘Fuego’, 3,5-dimethoxytoluene in ‘Red Eagle’, and 2-methylhexane in both cultivars. The total volatile content was maintained in ‘Fuego’ petals during the 6-day vase life, despite the changes in the content of individual volatile compound. By contrast, the total volatile content of ‘Red Eagle’ petals significantly decreased during vase life. Additionally, the volatile compounds that increased in content were relatively small molecules (<= C-8), whereas those that decreased in content during vase life were relatively large molecules (>= C-9). These results suggest that the analysis of volatile changes during vase life contribute to the harvest time selection of rose flowers and the determination of petal stages used for essential oil in many rose varieties.

A Cd(II) coordination polymer based on a polytopic compartmental ligand was synthesized, and used as an efficient heterogeneous catalyst for the Knoevenagel reaction between benzaldehyde and malononitrile under mild reaction conditions. The solid catalyst was characterized using single crystal XRD, X-ray powder diffraction, SEM, TGA, UV diffuse reflectance, infrared spectroscopy and elemental analysis. The compound is a two-dimensional (2D) MOF with a grid structure. Topological analysis of the framework revealed that it is a 2,4-connected binodal net. The catalytic activity was tested between various benzaldehydes containing different substituents with malononitrile. The effect of reaction parameters such as solvent, time, reactant ratio and catalyst amount was investigated. Furthermore, the catalyst stability was examined through reusability experiments and it is observed that the catalyst can be recycled at least five times without significant drop in its activity.

Here, we report the reaction between N-phenyl-o-phenylenediamine and pyrrole-2-carboxaldehyde to afford the N-phenyl-o-phenyl-enediiminopyrrole ligand {L-H2} in quantitative yield. A one-pot reaction between {L-H2} and diethylzinc (ZnEt2) in a 2:1 ratio afforded the homoleptic zinc metal complex [{L-H}(2)Zn] (1). The solid-state structures of ligand {L-H2} and zinc complex 1 were confirmed using X-ray crystallography. Further, complex 1 was used for chemoselective hydroboration of aldehydes and ketones in the presence of pinacolborane (HBpin) at ambient temperature to produce the corresponding boronate esters in high yield.

An efficient silver-catalyzed para-selective amination and aminative dearomatization of phenols with azodicarboxylates was developed. It afforded the para-aminophenols or amino cyclohexadieneones from free phenols depending on whether it has a para-substituent. The reaction proceeded smoothly in water under simple and mild conditions, giving the highly selective products in good yields within a short reaction time. It also showed broad substrate scope and good functional group compatibility.

The reactions of 3-benzyl-1,5-ditosyl-1,3,5-triazapentane (1) and 3-benzyl-1,5-dimesityl-1,3,5-triazapentane (2) with one equivalent of Lappert’s germylene or stannylene (M[N(SiMe3)(2)](2), where M = Ge, Sn) produced germylenes and stannylenes of the general formula PhCH2N(CH2CH2NR)(2)M, where M = Ge, R = 4-MeC6H4SO2- (3); 2,4,6-Me3C6H2- (5); M = Sn, R = 4-MeC6H4SO2- (4); 2,4,6-Me3C6H2- (6), in satisfactory yields. According to NMR data (H-1, C-13, Sn-119), stannylenes 4 and 6 are monomeric in solution, and the coordination number of tin is four. The synthesized stannylenes exhibited very high (compound 4) and moderate (compound 6) activity as initiators for bulk polymerization of epsilon-caprolactone, resulting in the synthesis of high-molecular-weight polymers with relatively narrow molecular-weight distribution. Previously unknown triamine 2 was synthesized by benzylation of HN(CH(2)CH(2)NHMes)(2) with benzyl chloride in the presence of K2CO3.

4-Hydroxy-3-methyl-2(1H)-quinolone (1), a molecule known for a long time and recently discovered from a Brassicaceae plant Isatis tinctoria without providing sufficient evidence to support the structure, was isolated from a fermentation extract of Burkholderia sp. 3Y-MMP isolated from a soil by a Zn2+ enrichment culture. Detailed spectroscopic analyses by MS and NMR, combined with C-13 chemical shift comparison with literature values of the related compounds and a synthetic preparation of 1, allowed its first full NMR characterization and identification of 2-quinolone but not 2-quinolinol (2) as the preferred tautomer for this heterocyclic system. While the metal-chelating activity was negligible, compound 1 at 10 mu M, a concentration lower than that in liquid production cultures, quenched hydroxy radical-induced chemiluminescence emitted by luminol by 86%. Because some Burkholderia species are pathogenic to plants and animals, the above result suggests that 1 is a potential antioxidant to counteract reactive oxygen species-based immune response in the host organisms.

Recommanded Product: 98-17-9. I found the field of Pharmacology & Pharmacy very interesting. Saw the article Cinnamonitrile Adjuvants Restore Susceptibility to beta-Lactams against Methicillin-Resistant Staphylococcus aureus published in 2019, Reprint Addresses Mobashery, S (corresponding author), Univ Notre Dame, Dept Chem & Biochem, Notre Dame, IN 46556 USA.. The CAS is 98-17-9. Through research, I have a further understanding and discovery of 3-(Trifluoromethyl)phenol.

beta-Lactams are used routinely to treat Staphylococcus aureus infections. However, the emergence of methicillin-resistant S. aureus (MRSA) renders them clinically precarious. We describe a class of cinnamonitrile adjuvants that restore the activity of oxacillin (a penicillin member of the beta-lactams) against MRSA. The lead adjuvants were tested against six important strains of MRSA, one vancomycin-intermediate S. aureus (VISA) strain, and one linezolid-resistant S. aureus strain. Five compounds out of 84 total compounds showed broad potentiation. At 8 mu M (E)-3-(5-(3,4-dichlorobenzy1)-2-(trifluoromethoxy)phenyl)-2-(methylsulfonyl)acrylonitrile (26) potentiated oxacillin with a >4000-fold reduction of its MIC (from 256 to 0.06 mg.L-1). This class of adjuvants holds promise for reversal of the resistance phenotype of MRSA.

Molecular oxygen is the most important green-oxidant due to its excellent properties. However, the effective utilization of molecular oxygen remains a major challenge in modern chemistry. Herein, we report the development a rapid, green and efficient microwave-assisted protocol for the air oxidation of boronic acids to phenols and alcohols under transition metal-free conditions. In the presence of KOH and DMSO, high yields of the expected phenols and alcohol were obtained with microwave-assistance, and a variety of functional groups were tolerated in this procedure. Notably, this transition metal-free method represents a breakthrough in both organic synthesis and green chemistry for the oxidative hydroxylation of boronic acids to phenols and alcohols.
