N-Acetonyl- and N-phenacyl quaternary salts of α-methyl substituted heterocycles 16, 17, 21, 23 and 26 were converted with DMFDMA into the corresponding 3-acylpyrrolo[1,2-a]pyridine 18, 7-benzoylpyrrolo-[1,2-c]pyrimidine 22, and 6-benzoylpyrrolo[1,2-a]pyrazine derivatives 24 and 27. A concurrent reaction produced methyl and phenyl substituted pyrrolo[1,2-x]azines 19, 20, 25 and 28.
Ñ -Acetonyl-和Ñ α甲基的-phenacyl季盐取代的杂环16,17,21,23和26被转换用DMFDMA成相应的3-acylpyrrolo [1,2一]吡啶18,7- benzoylpyrrolo- [ 1,2- c ]嘧啶22和6-苯甲酰基吡咯并[1,2- a ]吡嗪衍生物24和27。甲并发反应生成甲基和苯基取代的吡咯并[1,2- X ]吖嗪19,20,25和28。
