An effective approach to the enantiomers of alicyclic β-aminonitriles by using lipase catalysis
摘要:
Lipase-catalyzed N-acylations of racemic cis- and trans-2-aminocyclopentane- (and cyclohexane-) carbonitriles with 2,2,2-trifluoethyl butanoate in tert-butyl methyl ether (TBME) and in room-temperature ionic liquids (RTILs) were studied. The racemates were effectively resolved (E > 200) on a preparative scale by lipase PS-C II (lipase from Burkholderia cepacia) in TBME, resulting in two enantiomers in their enantiopure forms at 50% conversion. The reactions in RTILs with Novozym 435 (Candida antarctica lipase B) were slow and proceeded with low enantio selectivity. (c) 2005 Elsevier Ltd. All rights reserved.
