Cytotoxic pyrido[1,2-e]purines are readily available from 8,9-diallylpurines by ring-closing metathesis (RCM) followed by oxidation. The 8,9-diallylpurines were synthesized conveniently by addition of allylmagnesium bromide to the corresponding C-8 unsubstituted purines, followed by rearomatization of the adducts.
细胞毒性的吡啶并[1,2- e ]嘌呤很容易从8,9-二烯丙啶中通过闭环复分解(RCM)然后进行氧化而获得。通过将烯丙基溴化镁添加到相应的C-8未取代的嘌呤中,然后加合物进行重新麦芽糖化,可以方便地合成8,9-二烯丙基尿烷。
