The possibility of preparing 1,2,3,4,6,7,8,9-octahydro-5H-pyrrolo[3,2-c:4,5-c']dipyridines using the Piloty-Robinson reaction has been studied under various conditions. A novel method is proposed for the synthesis of the aromatic 3,6-diazacarbazole (5H-pyrrolo[3,2-c:4,5-c']dipyridine) from 2,8-dibenzoyl-1,2,3,4,6,7,8,9-octahydro-5H-pyrrolo[3,2-c:4,5-c']dipyridine obtained for the first time by the
在Piloty-Robinson反应中研究了制备1,2,3,4,6,7,8,9-八氢-5H-吡咯并[3,2-c:4,5-c']二吡啶的可能性各种条件。提出了一种由2,8-二苯甲酰基-1,2,3,4合成芳族3,6-二氮咔唑(5H-吡咯并[3,2-c:4,5-c']二吡啶)的新方法通过Piloty-Robinson方法在热条件下首次获得的6,7,8,9-八氢-5H-吡咯并[3,2-c:4,5-c']二吡啶。
