Enantioselective Ring-Opening Reaction of meso-Epoxides with ArSeH Catalyzed by Heterometallic Ti−Ga−Salen System
摘要:
[GRAPHICS]The first example of enantioselective ring-opening reaction of meso-epoxides with aryl selenols to give optically active beta-arylseleno alcohol in up to 97% ee was realized, using a chiral Ti-Ga-Salen heterometallic catalyst. A strong synergistic effect of different Lewis acids in the system was exhibited in the catalytic process.
