Methyl N-methyl-N-(6-substituted-5-nitropyrimidin-4-yl)glycinates (4a-n), obtained from 6-substituted-4-chloro-5-nitropyrimidines and sarcosine methyl ester (methyl 2-(methylamino)acetate), in the reaction with sodium alkoxides underwent transformations to give different products. N-methyl-N-(5-nitropyrimidin-4-yl)glycinates (4a,i,j) bearing amino and arylamino groups in the position 6 of the pyrimidine
N-甲基-N-(6-取代的5-硝基嘧啶-4-基)甘氨酸甲酯(4a-n),由6-取代的4-氯-5-硝基嘧啶和肌氨酸甲酯(2-(甲基氨基甲基) )乙酸盐),在与醇钠的反应中进行转化,得到不同的产物。在嘧啶环的6位带有氨基和芳基氨基的N-甲基-N-(5-硝基嘧啶-4-基)甘氨酸盐(4a,i,j)给出相应的6-取代的-4-甲基氨基-5-亚硝基嘧啶(5a,i,j)。在N-(6-烷基氨基-5-硝基嘧啶-4-基)-N-甲基甘氨酸盐(4b,fh用醇钠形成相应的6-烷基氨基-4-甲基氨基-5-亚硝基嘧啶(5b,fh)和5-羟基-8-甲基-5,8-二氢蝶啶-6,7-二酮(6b,fh)。后处理后,N-(6-二烷基氨基-5-硝基嘧啶-4-基)-N-甲基甘氨酸盐(4c-e,k,l)反应的主要产物是相应的6-二烷基氨基-9-甲基嘌呤-8-酮(7c-e,k,1)和8-烷氧基-6-二烷基氨基-9-甲基嘌呤(9c,1,10c,1)。甲基Ñ甲基ñ
