Asymmetric Synthesis of β-Substituted γ-Lactams via Rhodium/Diene-Catalyzed 1,4-Additions: Application to the Synthesis of (R)-Baclofen and (R)-Rolipram
摘要:
An efficient rhodium/diene-catalyzed asymmetric addition of arylboronic acids to alpha,beta-unsaturated gamma-lactams has been developed. The power of this methodology is further demonstrated by the concise synthesis of (R)-baclofen and (R)-rolipram.
