Application of the Evans aziridination procedure to 2-substituted acrylates and cinnamates: An expedient route to α-substituted α- and β-amino acids
摘要:
Reaction of the title compounds with Phl=NSO2Ar (Ar = p-tolyl or p-nitrophenyl) in the presence of catalytic copper (II) triflate in acetonitrile gave the corresponding 2 and/or 3-substituted aziridine-2-carboxylates in generally; good yields. The latter, on reaction with nucleophiles, gave alpha-substituted alpha- or beta-amino acids depending on the pattern of substitution on the aziridine ring. (C) 1998 Elsevier Science Ltd.
