We synthesized poly-substituted pyrrole derivatives 4a–e, 7a–c and 10a–d from the reaction of phenacyl bromide and the aza-Baylis–Hillman adducts 1a–d or their rearranged derivatives 5a–e. The pyrroles were synthesized via the successive N-alkylation, Michael addition, elimination of p-toluenesulfinic acid and oxidative aromatization processes.
我们通过苯甲酰溴与氮杂-Baylis-Hillman加合物1a - d或其重排衍生物5a - e的反应合成了多取代的吡咯衍生物4a - e,7a - c和10a - d。通过连续的N-烷基化,迈克尔加成,消除对甲苯亚磺酸和氧化芳构化过程来合成吡咯。
