We have developed a new methodology for the construction of 5-substituted pyrrolo[2,3-d]pyrimidines that involves the reduction of a nitroalkane to an oxime using the reducing ability of the Sn(SR3)− species, followed by mild, acid-catalysed deoximation of the resulting adduct using Dowex-H+ resin to form an intermediate aldehyde that spontaneously cyclises to the fused pyrrole ring.
我们已经开发出了一种用于构建5取代的吡咯并[2,3- d ]嘧啶的新方法,该方法涉及利用Sn(SR 3)-的还原能力将硝基烷还原为肟,然后进行温和的,使用Dowex-H +树脂对所得加合物进行酸催化脱氧,形成中间体醛,该醛自发环化成稠合的吡咯环。
