Thieno[2,3-d]pyrimidines with benzylsulfanyl and allylsulfanyl group in the presence of other alkylsul-fanyl substituents react selectively under mild conditions with secondary amines under replacement of the benzyl or allyl residue whereas the other substituents remain intact. This enables the synthesis of different basic substituted derivatives with potentially biologically activity.
在存在其他烷基硫代-芳基取代基的情况下,具有苄基硫烷基和烯丙基硫烷基的噻吩并[2,3- d ]嘧啶在温和的条件下与仲胺选择性地反应,取代了苄基或烯丙基残基,而其他取代基则保持完整。这使得能够合成具有潜在生物学活性的不同的碱性取代的衍生物。
