Novel substituted 2-(6-benzyl-5-oxo-3-phenyl-(S3,7S,7AR)- perhydroimidazol (1,5-C) (1,3) thiazol-7YL) compounds

摘要

A novel route has been developed for substituted 2-[-6-benzyl-5-oxo-3-phenyl-(3s,7s,7aR)-perhydroimidazol[1,5-c][1,3]thiazol] compounds; crucial intermediates for D(+)-biotin of formula (7) which involves simple, efficient, practical and cost effective protocol. These are crucial intermediates for commercially important D(+)-biotin preparation. These compounds are more stable and are produced by non-hazardous methods.
