A new method for the preparation of 2,2,3-trisubstituted methyl 1-benzoylaziridine-2-carboxylates is reported. These compounds have been obtained starting from α-alkyl β-amino acids by formation of the lithium dianion and reaction with iodine. The aziridines undergo ring expansion or ring opening, depending on the substituents of the aziridine ring and on the reaction conditions. Following these methods
报道了一种制备 2,2,3-三取代甲基 1-benzoylaziridine-2-carboxylates 的新方法。这些化合物是从α-烷基β-氨基酸开始,通过形成锂二价阴离子并与碘反应获得的。氮丙啶会发生扩环或开环,这取决于氮丙啶环的取代基和反应条件。按照这些方法,已经合成了α-取代的α-羟基β-氨基酸和α-取代的β-羟基α-氨基酸。
