  Heterocycles 30: Lipase catalyzed kinetic resolution of racemic 1-(2-aryl-4-methyl-thiazol-5-yl)ethanols

  摘要：

  The lipase mediated selective O-acylation and alcoholysis of the corresponding alcohols/butanoates have been investigated for the production of both (R)- and (S)-1-(2-aryl-thiazol-5-yl)ethanols. In terms of stereoselectivity and activity, CaL-B mediated selective acylation gave similar good results (c = 50%, E >> 200) in comparison with CaL-A mediated alcoholysis (c = 50%, E >> 200). Using the sequential kinetic resolution: first a CaL-B catalyzed (R)-selective O-acylation of racemic alcohols rac-2a-d followed by a CaL-A mediated methanolysis of the previously obtained enantiomerically enriched (R)-butanoates (R)-3a-d yielded (with 39-46% yields) both enantiopure forms of the 1-(2-aryl-thiazol-5-yl)ethanols.
