Catalytic Asymmetric Synthesis of Diarylacetates and 4,4-Diarylbutanoates. A Formal Asymmetric Synthesis of (+)-Sertraline
摘要:
The intermolecular C-H insertion chemistry of phenyldiazoacetates catalyzed by dirhodium tetrakis((S)-N (dodecylbenzenesulfonyl)prolinate) (Rh-2(S-DOSP)(4)) can be effectively carried out on cyclohexadienes, leading to the asymmetric synthesis of diarylacetates. The reaction of vinyldiazoacetates with cyclohexadienes results in an unprecedented carbenoid reaction that is formally a combined C-H insertion/Cope rearrangement. The synthetic utility of this novel transformation was demonstrated by its utilization in a formal asymmetric synthesis of (+)-sertraline.
