A novel and stereospecific synthesis of (+)-preussin
Raghavan, Sadagopan,Rasheed, M. Abdul
, p. 10307 - 10312 (2007/10/03)
A novel and stereospecific approach to (+)-preussin that would permit the synthesis of analogs for structure activity relationship studies, is disclosed. The key step includes the regio- and stereoselective elaboration of a bromohydrin via intramolecular sulfinyl group participation.
