The Hooker oxidation is one of the most intriguing transformations wherein lapachol (1) is readily converted to norlapachol (2) in very good yield. This one-pot reaction involves a very intricate mechanism in which the alkyl side chain of lapachol is

A stereoselective synthesis of N-Boc-protected cis-(2R,3S)-3-hydroxy pipecolic acid, starting from d-glucose is described. The key step in the overall synthesis is a highly regioselective reductive cleavage of benzylidene acetal 13 leading to hydroxy

A mild and highly efficient one-pot method has been developed for the stereoselective synthesis of structurally diverse novel iminosugar C-aryl glycosides. The generality of this methodology is demonstrated with a wide variety of aryl nucleophiles an
