Asymmetric transformation in photoequilibrium systems: diastereoselective isomerization of N-(R)-(+)-α-arylethylfluorene-9-spiro-1′-cyclopropane-2′-carboxamide derivatives
Abstract
Photochemically induced asymmetric transformation in the isomerizations of N-(R)-(+)-α-arylethylfluorene-9-spiro-1′-cyclopropane-2′-carboxamide derivatives showed moderate to high diastereoselectivity.
