On the basis of ideas recently advanced regarding the origin of enantioselectivity in the OsO4 promoted dihydroxylation of olefins catalyzed by bis-cinchona alkaloid derivatives such as 1, specifically strong evidence for reaction via transition state assembly 2, the mono-quinidine derivative 3 was selected as a promising catalytic ligand.The experimental observation of high enantioselectivity promoted by 3 provides additional evidence in favor of transition-state 2.
