Treatment of the sulfoxide (I) with N-phenyl and N-methoxyphenyl aldimines allows highly stereoselective access to syn-sulfanyl amines.
Diastereoselective quaternization of ortho-sulfinylbenzyl-methylpropargylic carbanions is carried out with various allylic, propargylic, and benzylic halides.
The ability to establish switchable site-selectivity through catalyst control in the direct functionalization of molecules that contain distinct C–H bonds remains a demanding challenge that would… (More)
Abstract The self induced diastereoselective oxidation of several thio-β- d -galactopyranosides to the corresponding sulfoxides, has been shown to occur in high yield. Up to 74% diastereomeric excess… (More)
Abstract Sulfinylglycosides are efficiently activated by the system TfOH/TEP in the glycosylation reaction to afford disaccharides in good yields.
