Three series of sulfonate derivatives of paeonol were synthesized and screened in vitro for their anti-oomycete activity against P. capsici, respectively. Among all the compounds, 4m displayed the best promising and pronounced anti-oomycete activity against P. capsici than zoxamide, with the EC50 values of 24.51 and 26.87 mg/L, respectively. The results show that acetyl and 4-OCH3 are two necessary groups. The existence of these two sites is closely related to the anti-oomycete activity. Relatively speaking, hydroxyl group is well tolerated, and the results showed that after modification of hydroxyl group with sulfonyl, the anti-oomycete activity was significantly increased.

The 2-Aminonicotinonitrile derivative was reacted with different bi-functional reagents such as formamide, thiourea, acetic anhydride, and phthalic anhydride under optimized conditions to give pyrimidine, thiourea, acetamide, and isoindoline derivatives, respectively, When it was treated with active methylene reagents as malononitrile, phenacyl bromide, and ethyl bromoacetate under varied experimental modulation, it afforded 1, 8-naphthyridine, ethyl, and methylamino nicotinonitrile derivatives, respectively. Also, it was reacted with p-toluene sulfonyl chloride, chloroacetyl chloride, and benzoyl chloride to give sulfonamide, 2-chloro-N-acetamide, and benzamide derivatives, respectively. Likewise, it was reacted with diethyl malonate, ethyl cyanoacetate, and cyano acetic acid to give ethylpropanoate, naphthyridine, and cyano acetamide derivatives, respectively. However, treatment of ethylpropanoate and cyano acetamide derivatives with hydrazine hydrate gave pyrazole and 5-amino-pyrazole nicotinonitrile derivatives, respectively. In addition, it was reacted with p-anisaldehyde, phenyl isocyanate, and triethyl orthoformate to give benzylamino nicotinonitrile, phenyl urea, and N-formamide derivatives, respectively. Furthermore, it was reacted with nitrous acid then coupled with aniline; it was also reacted with isatine and 1,3- dibromo propane to give oxoindoline derivative, and the dimer. Elemental analyses, together with spectroscopic data including IR, H-1-NMR in addition to C-13-NMR and mass spectra submit proofs for the chemical structures for all compounds. [GRAPHICS]

A unique photoinduced reaction that couples a triarylphosphine, an alkene, and water to produce 2-(cyclohexa-2,5-dienyl)ethylphosphine oxide is reported herein. The alkene inserts into a C(aryl)-P bond of the arylphosphine, the aryl ring is dearomatized into the cyclohexadienyl ring, and the phosphorus is oxidized. The three components are all readily available, and their intermolecular coupling significantly increases molecular complexity. The products formed are applicable to the Wittig olefination.

DNA-encoded combinatorial chemical library (DEL) technology, an approach that combines the power of genetics and chemistry, has emerged as an invaluable tool in drug discovery. Skeletal diversity plays a fundamental importance in DEL applications, and relies heavily on novel DNA-compatible chemical reactions. We report herein a phylogenic chemical transformation strategy using DNA-conjugated benzoyl hydrazine as a common versatile precursor in azole chemical expansion of DELs. DNA-compatible reactions deriving from the common benzoyl hydrazine precursor showed excellent functional group tolerance with exceptional efficiency in the synthesis of various azoles, including oxadiazoles, thiadiazoles, and triazoles, under mild reaction conditions. The phylogenic chemical transformation strategy provides DELs a facile way to expand into various unique chemical spaces with privileged scaffolds and pharmacophores.

We report the shortest synthesis of glycosidase inhibitor (+)-hyacinthacine A(1) using a highly chemoselective N-heterocyclic carbene-catalyzed crossbenzoin reaction as well as a furan photooxygenation-amine cyclization strategy. This is the first such cyclization on a furylic alcohol, an unprecedented reaction due to the notorious instability of the formed intermediates. The photooxygenation strategy was eventually incorporated into a three-step one-pot process that formed the requisite pyrrolizidine framework of (+)-hyacinthacine A(1).

An efficient and convenient uranyl-catalyzed reductive hydrosilylation reaction of para-quinone methides (p-QMs) was developed by employing silane as the reductant. The hydrosilylation procedure using the UO2(NO3)(2)center dot 6H(2)O/Et3SiH catalytic system proceeded smoothly and provided an expedient method for the construction of various diarylmethane derivatives in one step with good to excellent yields.

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.

Catalytic oxidation of alcohols containing heteroatoms with molecular oxygen is usually rather challenging, as transition metal catalysts are easily deactivated by heteroatoms. In contrast to conventional results, herein facile oxidation of 2-pyridinemethanol with dioxgyen was observed over simple vanadium catalysts including VOSO4 or VO(acac)(2), which seemed much easier than that of benzyl alcohol. 2-Pyridinemethanol could coordinate with the vanadium center, which would promote oxidation of 2-pyridinemethanol itself, rather than deactivate vanadium catalysts. This study would provide a new clue to develop efficient catalysts for transformations of heterocyclic compounds.
