与二酮吡咯并吡咯(DPP)颜料有关的合成研究。第1部分:寻找烯基-DPP。标准DPP合成中的不饱和腈:新型环戊[ c ]吡咯烷酮发色团
摘要:
4,5-二氢-5-氧代-2-苯基吡咯-3-羧酸乙酯的阴离子与丙烯腈和各种二烯的狄尔斯-阿尔德加合物的反应很少产生预期的DPP衍生物。与环己-3-烯腈的反应提供了一个值得注意的例外:所生成的环己烯基-DPP的热解产生了丁二烯和不纯的3-乙烯基-6-苯基-DPP,后者是热不稳定的。当上述阴离子与α,β-不饱和腈反应时,迈克尔加成反应占主导:丙烯腈和甲基丙烯腈产生4,4-双(氰基乙基)和4,4-双(2-氰基丙基)衍生物,以及肉桂腈,取代的肉桂腈和3-( 2-噻吩基)丙烯腈得到深红色的3-芳基-5-氰基-4-羟基-2 H-环戊[ c ]吡咯-1-酮。这些亲核试剂两可可经历Ñ-和根据所用烷基化剂的O-或C-烷基化。
