  摘要：

  The synthesis of both enantiomers of 1-(10-ethyl-10H-phenothiazin-1,2, and 4-yl)ethanols 1a-c and their acetates via enantioselective methanolysis of the corresponding racemic esters rac 2a-c with lipase B from Candida antarctica (CaL-B) or/and by acylation of the racemic alcohols with the lipase A or lipase B from C antarctica (CaL-A and CaL-B) is described. The absolute configuration of enantiopure 1-(10-ethyl-10H-phenothiazin-1-yl)ethyl acetate 2a was assigned as (R) by using QM/MM(hf/3-21g:uff) calculations within the CaL-B (1LBT crystal structure) enzymic environment.
