Two tri(benzo[b]thiopheno)subporphyrazine regioisomers with C3 and C1 molecular symmetry have been isolated from the cyclotrimerization of benzo[b]thiophene‐2,3‐dicarbonitrile as the first five‐membered‐heterocycle‐fused subphthalocyanineanalogues. Optical resolution of both regioisomers was achieved by using a chiral HPLC technique, affording the firstchiralsubphthalocyanineanalogues.
从苯并[ b ]噻吩-2,3-二碳腈的三环化中分离出两个具有C 3和C 1分子对称性的三(苯并[ b ]噻吩基)亚卟啉区域异构体,作为第一个五元杂环稠合的亚酞菁类似物。通过使用手性HPLC技术获得两种区域异构体的光学拆分,得到了第一个手性亚酞菁手性类似物。
