Abstract:
Two different chemoenzymatic approaches allowed the preparation of the
enantiomers of desoxymuscarine 5, a muscarinic receptor agonist.
Transesterification of racemic 5-hexen-2-ol 7 with vinyl butyrate under
the catalysis of Candida antarctica B lipase was the key step for the
preparation of (-)-5 (2R,5R). On the other hand, lipase PS-catalyzed
hydrolysis of iodo butyrate (+/-)-14 was utilized to obtain (+)-5
(2S,5S). Both enantiomers were prepared with enantiomeric excesses
higher than 98\%. (C) 1998 Elsevier Science Ltd. All rights reserved.
