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 enantioselectivity.

Six-membered platinum(II) complexes of 2-(aminomethyl)cyclohexylamine (=amcha), whose four isomers are (1R,2R)-, (1S,2S)-, (1R,2S)-, and (1S,2R)-amcha, were synthesized.The conformations of Cl2, Cl2. Cl2, and Cl2 were determined by 1H-NMR, 13C-NMR, and CD spectra.It is proposed that Cl2 and Cl2 take a fixed chair form with a dihedral angle (Pt-N-C(1)-C(6)) of 180 deg, while Cl2 and Cl2 are interconverting between two chair forms.
