Abstract

A stereoselective synthesis of 2,3-dihydro-1H-indoles with a RhII-catalyzed C–H insertion is reported. The α-diazo carbonyl intermediates can be obtained by a diazo-transfer reaction of 2-aminophenylacetic acids. Optimization and kinetic studies were performed, which resulted to increased yields of the diazo transfer after mechanistic evaluation of the side-product formation. trans-2,3-Dihydro-1H-indoles were obtained in high diasteromeric excesses (up to 94 % de) and enantiomeric excesses (up to 94 % ee).
