제목 Kinetic Resolution of Asymmetric Ring Opening reaction using Sulfonic acid Catalyzed by Heterometallic Chiral (Salen) Co Complex
초록 The binuclear chiral (Salen) Co complexes bearing Lewis acids of Al and Ga catalyze regio- and enantioselective ring opening of terminal epoxides with sulfonic acids and TBAC series. Reaction condition that made ee>99% and yield >49% (maxima=50%) were studied. The ring opened product of terminal epoxide with sulfonic acids can not followed by cyclization step in the presence of catalyst and base. Strong synergistic effects of different Lewis acid of Co-Al and Co-Ga were exhibited in the catalytic process.
