A synthesis of deoxyvariolin B (5) is described. The tricyclic pyridopyrrolopyrimidone (11) was prepared from 7-azaindole via lithiation at C-2, introduction of an aminoethyl side-chain, then closure of the third ring. A heteroaryl palladium(0)-catalysed coupling reaction was used to introduce a pyrimidine substituent at C-5.
描述了脱氧variolin B(5)的合成。三环吡咯并吡咯并嘧啶酮(11)是由7-氮杂吲哚通过在C-2处锂化,引入氨乙基侧链,然后闭合第三环而制备的。杂芳基钯(0)催化的偶联反应用于在C-5处引入嘧啶取代基。
