摘要：

[GRAPHCIS] Optically active beta -ketoiminato cationic cobalt(lll) complexes were synthesized as effective Lewis acid catalysts for the enantioselective carbonylene reaction, In the presence of a catalytic amount of cobalt(lll) hexafluoroantimonate derived from the optically active 1,2-diphenyl-1,2-ethanediamine, the carbonyl-ene reaction with a variety of alkenes and glyoxal derivatives smoothly proceeded to afford the corresponding homoallylic alcohols in good-to high yields with high enantioselectivities.
