Rh‐Catalyzed Chemodivergent Parallel Kinetic Resolution and Desymmetrization of Enynes and Dienynes with Acrylamides

Angewandte Chemie, EarlyView.
Rh‐catalyzed chemodivergent parallel kinetic resolution of racemic 1,6‐enynes with α‐fluoroacrylamides or mixtures of different acrylamides proceeded via [2+2+2] cycloaddition and C–H alkylation to afford structurally and stereochemically distinct products with high selectivity under mild conditions.
