A one-pot synthesis of 1, 3 and 4-cyanophenothiazines and a two-step approach to 2-cyanoisomer have been developed. The condensation of 2-aminobenzenethiol and 2,3 or 3,4-dihalogenobenzonitriles followed by Smiles rearrangement or by intramolecular aromatic substitution gave the desired ring systmes.
已开发出一锅合成1、3和4-氰基吩噻嗪和两步合成2-氰基异氰酸酯的方法。2-氨基苯硫醇和2,3或3,4-二卤代苄腈的缩合,然后进行Smiles重排或分子内芳族取代,得到了所需的环系统。
