Scope and Mechanistic Analysis of the Enantioselective Synthesis of Allenes by Rhodium-Catalyzed Tandem Ylide Formation/[2, 3]-Sigmatropic Rearrangement between Donor/Acceptor Carbenoids and Propargylic Alcohols
Rhodium-catalyzed reactions of tertiary propargylic alcohols with methyl aryl- and styryldiazoacetates result in tandem reactions, consisting of oxonium ylide formation followed by [2, 3]-sigmatropic rearrangement. This process competes favorably with the standard O—H insertion reaction of carbenoid...
