The synthesis of 1-((S)-3-acetylthio-2-methylpropanoyl)-L-prolyl-L-phenylalanine 1 (alacepril, code name : DU-1219), a clinically used antihypertensive agent, and one of its active metabolites, 1-((S)-3-mercapto-2-methylpropanoyl)-L-prolyl-L-phenylalanine 2 (code name : DU-1227), is described. The application of chloral to the N-formylation of L-proline is also described. The presence of an intramolecular hydrogen bond in the trans conformer of 1 in solution is suggested on the basis of spectroscopic examinations of 1 and its ethyl ester 4.
报道了临床使用的抗高血压药物1-((S)-3-乙酰巯基-2-甲基丙酰基)-L-脯氨酰-L-苯丙氨酸1(阿拉普利,代码名:DU-1219)及其活性代谢物之一1-((S)-3-巯基-2-甲基丙酰基)-L-脯氨酰-L-苯丙氨酸2(代码名:DU-1227)的合成。还描述了氯醛在L-脯氨酸N-甲酰化中的应用。根据1及其乙酯4的光谱检查结果,推测溶液中1的反式构象分子内存在氢键。
