The total synthesis of prodigiosin (1), possessing the characteristic pyrrolylpyrromethene skeleton of a class of naturally-occurring polypyrroles, is detailed, The approach is based on the application of an inverse electron demand Diels-Alder reaction of dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate in a 1,2,4,5-teirazine → 1,2-diazine → pyrrole strategy for preparation of prodigiosin pyrrole ring
详细介绍了具有一类天然存在的聚吡咯的特征吡咯基吡咯亚甲基骨架的prodigiosin(1)的全合成,该方法基于二甲基1,2,4的反电子需量Diels-Alder反应的应用, 1,2,4,5-替拉嗪中的5-四嗪-3,6-二羧酸→1,2-二嗪→吡咯策略,用于制备pro原苷吡咯环B,并随后实施分子内钯(II)促进2 ,2'-二芳基(2,2'-联吡咯)偶联用于构建prodigiosin 2,2'-联吡咯AB环系统。
