found to be highly active for obtaining α,β‐unsaturated esters (up to 95 % yield and with high diastereoselectivities) from a variety of benzyl, heteroaryl, allyl and alkyl alcohols via one‐pot alcohol oxidation‐Wittigreaction. The transformation utilizes air as the stoichiometric oxidant, and the inexpensive catalyst can be recovered and reused.
Characterization of FabG and FabI of the<i>Streptomyces coelicolor</i>Dissociated Fatty Acid Synthase

Functional crosstalk: β‐Ketoacyl‐acyl carrier protein (ACP; FabG) and enoyl‐ACP reductase (FabI) from Streptomyces coelicolor were identified and characterized. Kinetic analysis demonstrated that these enzymes process straight and branched‐chain substrates along with the ACPs from both fattyacid and undecylprodiginine biosynthetic pathways. This relaxed substrate specificity allow these enzymes to
oquinoline derivatives were synthesized and biologically evaluated. Among them, (S)-2-(E)-3-furan-2-ylacryloyl}-7-[(2E,4E)-5-(2,4,6-trifluorophenyl)penta-2,4-dienyloxy]-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (compound 17u) was identified as a potent protein tyrosine phosphatase 1B (PTP1B) inhibitor without peroxisome proliferator-activated receptor (PPAR) γ activation: PTP1B inhibition IC50=0
Cross-linked poly(4-vinylpyridine/styrene) copolymer-supported bismuth(III) triflate: an efficient heterogeneous catalyst for silylation of alcohols and phenols with HMDS

Cross‐linked poly(4‐vinylpyridine/styrene) copolymer‐supported bismuth(III) triflate (30P/S‐Bi) effectively activates hexamethyldisilazane (HMDS) for the silylation of alcohols and phenols. By the use of this heterogeneous catalytic system, a wide range of alcohols as well as phenols are converted into their corresponding trimethylsilyl ethers in high yield under mild reaction conditions. The catalyst was reused
