Ring-Opening Reaction (Ring-Open + reaction)
Selected AbstractsCatalytic Asymmetric Ring-Opening Reaction of meso -Epoxides with Aryl Selenols and Thiols Catalyzed by a Heterobimetallic Gallium-Titanium-Salen ComplexADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 6 2009Jiangtao Sun Abstract A chiral heterobimetallic Lewis acid complex has been developed as an efficient catalyst. The enantioselective desymmetrization of meso -epoxides with aryl selenols and thiols catalyzed by the heterobimetallic complex has been optimized. The optically active , -arylseleno alcohols and ,- hydroxy sulfides were obtained in good yields and high enantioselectivities (up to 97% ee and 92% ee, respectively). A strong synergistic effect between different Lewis acids was exhibited in the catalytic process.

The products were generally isolated in high yields and with high to excellent enantioselectivity. The catalytic system was studied by X-ray single crystal analysis. In experiments on non-linear effects a strong non-linear effect of the catalyst system was observed.
