“…Conjugate addition of nitroalkanes to enoates results in the formation of γ-nitro ester derivatives that can be reduced at the nitro group to give the corresponding γ-amino esters. Enzymatic resolution of product 365 obtained by conjugate addition of nitromethane to benzyl 2-trifluoromethylpropenoate 364 provides acid 366 and ester 367 that after simple separation can be reduced at the nitro group to afford γ-amino acid 368 and γ-amino ester 369 in almost enantiomerically pure form (Scheme ) 103 …”

“…In particular, kinetic resolution using lipases has been widely investigated thus far. For example, the preparation of optically active -amino acids 52 using lipase P as a resolving agent has been reported (Scheme 16) [66]. This synthesis involves the hydrolysis of the nitroalkyl benzyl ester 53 (prepared easily via Michael addition of nitro methane toward commercially available 2-CF 3 -acrylate, CH 2 =C(CF 3 )CO 2 Bn) by lipase P followed by hydrogenation of the nitro moiety.…”
