A Concise Asymmetric Synthesis of A β-Lactam-Based Cholesterol Absorption Inhibitor
摘要:
A concise, four-step, asymmetric synthesis of a beta-lactam-based cholesterol absorption inhibitor, Sch 57939, was developed, The discovery of a one-step enantio- and diastereoselective synthesis of a trans-beta-lactam provided easy access to the desired three chiral centers. A novel zinc phenoxide-promoted ether synthesis was reported for the completion of the side chain.
