An efficient synthesis of enantiomerically pure 3-hydroxy-β-lactams via zinc induced removal of a chiral auxiliary
摘要:
The diastereoselective synthesis of various beta-lactams 6a-d and 7a-d has been achieved using a chiral acid derived from (+)-+-carene. An efficient zinc induced cleavage of the o-halo ether linkage of these beta-lactams to give enantiomerically pure 3-hydroxy-cis-beta-lactams 8a,b and 9a-d is described.
