Abstract

Dynamic kinetic asymmetric transformation (DYKAT) of a series of 1, 5-diols has been performed in the presence of Candida antarctica lipase B (CALB), Pseudomonas cepacia lipase II (PS-C II), and ruthenium catalyst 4. The resulting optically pure 1, 5-diacetates are useful synthetic intermediates, which was demonstrated by the syntheses of both an enantiopure 2, 6-disubstituted piperidine and an enantiopure 3, 5-disubstituted ...
