The oxidation of 1,19-di-t-butoxycarbonyl-b-bilenes with bromine affords not only a major biliverdin, but also minor biliverdins. Elucidation of their structure revealed that cleavage of the b-bilene chain takes place during the oxidation, followed by dimerization of one dipyrrylmethene half. The synthesis of mesobiliverdins IX β , XI β, IV β , IX δ and coprobiliverdin II β are described.
1,19-二-叔丁氧基羰基-b-比林斯被溴氧化不仅提供了主要的胆绿素,还提供了次要的胆绿素。对它们的结构的阐明揭示了在氧化过程中发生了b-比林烯链的裂解,随后是一个二吡啶基亚甲基一半的二聚化。mesobiliverdins IX的合成β,XI β,IV β,IX δ和coprobiliverdin II β进行说明。
