研究了在固液相转移催化条件下, N-氰甲基苯甲亚氨酸酯的烷基化反应, 得到烷基化产物C-烷基化的亚氨酸酯, 烷基化产品不需进一步纯化就可水解得到α-氨基酸, 利用这一方法合成了十个α-氨基酸.

The solid-liq. phase transfer catalytic alkylation of Et N-(cyanomethyl)benzenecarboximidate I using solid K2CO3 as a base and Bu4N+Br- as a phase transfer catalyst was reported. The alkylated products without further puritication were hydrolyzed to give a-amino acids. Ten a-amino acids were synthesized with this method.

Key words: AMINO ACID, ETHYL ESTER, ALKYLATION, PHASE TRANSFER CATALYSIS, SYNTHESIS METHODS, BENZENEMETHANAMINE P, ACETONITRILE, IMIDIC ACID, NSFC
