At first, a series of L-amino ester hydrochloride were prepared through the SOCl2’s method and got better yield. After that the“Vilsmeier salts”were synthesized from oxalyl chloride and 1,3-dimethyl-2-imidazolidinone ,then reacted with amino acid ethyl ester hydrochloride in dichloromethane.
首先我们采用了SOCl2法合成了L-氨基酸乙酯的盐酸盐,之后采用草酰氯法:即用1,3-二甲基-2-咪唑啉酮与草酰氯生成“vilsmeier salt”,再与L-氨基酸乙酯盐酸盐反应生成五烷基手性胍,最后用碘甲烷卤代生成六烷基手性胍卤盐。
