Abstract 2‐Phenyl‐1,1,3‐tricyano‐3‐bromopropene 1 reacts with the aromatic amines 2a–f and 6a–c to afford the N‐substituted pyrroles 4a–d, the pyrrolo[1,2‐a]quinazoline derivatives 5a, b, and the diaza‐as‐indacene derivatives 7a–c and 8a–c, presumably via elimination of hydrogen bromide followed by cyclization of the formed acyclic intermediates. All structures are confirmed by analytical and spectral
摘要 2-苯基-1,1,3-三氰基-3-溴丙烯 1 与芳香胺 2a-f 和 6a-c 反应得到 N-取代的吡咯 4a-d,即吡咯并[1,2-a]喹唑啉衍生物 5a、b 和二氮杂茚衍生物 7a-c 和 8a-c,大概是通过消除溴化氢然后环化形成的无环中间体。所有结构均通过分析和光谱数据确认。
