4-bis-(amidomethylsulfanyl) pyrimidine-5-carbonitriles react selective in the 2-position with various secondary cyclic amines under mild conditions. The resulting pyrimidines were finally transformed into the corresponding thieno[2,3-d]pyrimidine-6-carboxylic acid amides which afford the synthesis of selective substituted thienopyrimidines.
高度官能化的杂环6-烷基-分别为6-芳烷基硫烷基-2,4-双-(酰胺基甲基硫烷基)嘧啶-5-腈在2-位与温和条件下的各种仲环状胺选择性反应。最后将得到的嘧啶转化为相应的噻吩并[2,3 - d ]嘧啶-6-羧酸酰胺,从而合成了选择性取代的噻吩并嘧啶。
