Chiral synthesis of (+)-aspicilin by using a furyl group as the masked γ-oxo-α,β-unsaturated carboxylic acid
摘要:
Synthesis of (+)-aspicilin is described. The decisive steps are the diastereoselective dihydroxylation of the key intermediate 2, the subsequent furan ring oxidation, and the chelation-controlled reduction of ketone 1. (C) 1997 Elsevier Science Ltd.
