Abstract
The enantioselective hydrogenation of alpha-methylene-1,3-dioxolan-2-o nes catalyzed by chiral (diphosphine)ruthenium complexes leads to opti cally active cyclic carbonates with high enantioselectivities. Their h ydrolysis in methanol in the presence of potassium carbonate quantitat ively affords optically active 1,2-diols.
