摘 要:以(S)-2-氨基丙醇和氯乙酰氯为起始原料,经酰化和环合反应制得(S)-5-甲基吗啉-3-酮(4);4经还原制得(S)-3-甲基吗啉(5);5与4-溴-2-甲基苯甲酸酰化缩合合成了(S)-(4-溴2-甲基苯基)(3-甲基吗啉)-甲酮,总收率57%,其结构经~1H NMR和^(13)C NMR确证。(S) -5-methylmorpholin-3-one (4) was obtained by the reaction of acylation and cyclization, using (S)-amino-l-propanol and chloroacetyl chloride as the starting materials. (S)-3-methylmorpho- line ( $ ) was synthesized by reduction of 4. (S) -(4-bromo-2-methylphenyl) ( 3-methylmorpholino ) methanone was synthesized by condensation reaction of 5 with (S) -3-methylmorpholine and 4-bromo-2- methylbenzoic acid, the total yield was 57%. The structure was confirmed by 1H NMR and 13C NMR.
