A straightforward preparation of both enantiomerically pure 2-O-benzyl-erythro-butanetetrols
摘要:
A short and efficient synthesis of both enantiomerically pure 2-O-benzyl-erythro-butanetetrols 4 and ent- 4 from the readily available D-erythronolactone 1 is presented. The synthesis proceeds in a highly efficient manner and is in both cases substrate controlled.
