The asymmetric ring-opening of epoxides with dithiophosphorus acids catalyzed by a(salen)Ti(IV) complex formed in situ from the reaction of Ti(OPr-i)4 and the chiral Schiff basederived from (1R,2R)-(+)-diaminocyclohexane was realized. The resulting products wereobtained with low to good enantioselectivity (up to 73% ee).
