CATALYTIC OXIDATION OF THIOLS TO DISULFIDES WITH VANADYL ACETYLACETONATE (VO(ACAC)2)

Catalytic amounts of VO(acac)2 coupled with t-butylhydroperoxide chemoselectively oxidizes thiols to disulfides under mild reaction conditions and is generally useful for a wide variety of thiols. *IICT communication No. 4400.

Novel, efficient and stereospecific synthesis of xylo-(2R,3S,4S)-phytosphingosine and threo-(2R,3R)-sphingosine ☆

Abstract The stereo- and regioselective elaboration of a bromohydrin from an olefinic precursor and Pummerer ene reaction for carboncarbon bond formation are the key steps in a novel and flexible synthesis of xylo -phytosphingosine and threo -sphingosine.

Stereoselective bromohydrin formation from β-hydroxy sulfoxides mediated by the pendant sulfoxide†‡

Regio- and stereo-selective bromohydrin formation promoted by a neighbouring sulfinyl moiety is disclosed.

Target alcohol/phenol release by cyclative cleavage using glycine as a safety catch linker

The utility of glycine as a safety catch linker for the immobilization of alcohols and phenols to the solid-support is demonstrated by performing a variety of synthetic transformations.
