title: The first five-membered-heterocycle-fused subphthalocyanine analogues: chiral tri(benzo[b]thiopheno)subporphyrazines.
abstract: 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 subphthalocyanine analogues. Optical resolution of both regioisomers was achieved by using a chiral HPLC technique, affording the first chiral subphthalocyanine analogues.
