Direct triphenylphosphine-mediated regioselective sulfenylation of glycals by using various cheap and easily available aryl sulfonyl chlorides as a sulfur source to generate different C2-S-aryl-glycosides was developed. Notably, the features of this protocol offer a milder and easier operational procedure, and broad substrate scope with complete regioselectivity at C-2. Experiments and DFT calculations supported the proposed mechanism and regioselectivity for the formation of C2-S-aryl-glycosides.
New Journal of Chemistry published new progress about Crystal structure. 4098-06-0 belongs to class esters-buliding-blocks, and the molecular formula is C12H16O7, Safety of (2R,3R,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate.
