An improved one-flask synthesis of various methyl 2-diazo-4-aryl and 4-heteroaryl-3-butenoates, precursors to donor/acceptor substituted carbenoids, is described. Their Rh2(S-DOSP)4 catalyzed reaction with 1-acetoxy-3,4-dihydronaphth

(equation presented) The intermolecular C-H insertion chemistry of phenyldiazoacetates catalyzed by dirhodium tetrakis((S)-N-(dodecylbenzenesulfonyl)prolinate) (Rh2(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.
