The use of 2, 6-dimethylmorpholine as an amine moiety in Mannich reaction has been investigated. Nine new Mannich bases have been synthesized using nine different ketones. The salts of β -amino esters have also been synthesized by Mannich reaction using p -nitrophenylacetic acid, formaldehyde solution (37 per cent), and three different amines (2, 6-dimethylmorpholine, piperidine, and 4-methylpiperidine)
已经研究了在曼尼希反应中使用2,6-二甲基吗啉作为胺部分。使用九种不同的酮合成了九种新的曼尼希碱。β-氨基酯的盐还可以通过对硝基苯乙酸,甲醛溶液(37%)和三种不同的胺类(2、6-二甲基吗啉,哌啶和4-甲基哌啶)通过曼尼希反应合成,然后进行酯化反应。这些化合物的结构已通过红外光谱,质谱和元素分析确定。
