Iodine-mediated intramolecular oxidative cyclization of 2-(styrylthio)anilines: Synthesis of 2-substituted benzothiazoles
A novel metal-free iodine-mediated intramolecular oxidative cyclization protocol is presented, which allows for the preparation of various 2-substituted benzothiazoles. Georg Thieme Verlag Stuttgart · New York.
Vicarious nucleophilic substitution of (chloroalkyl)heterocycles with nitroarenes
The vicarious nucleophilic substitution of potassium carbanions of the (chloromethyl)pyridines 1a and 1b, (chloromethyl)benzothiazole 1c, (chloromethyl)thiazole 1d, (chloroethyl)thiazole 1e and (chloroethyl) benzothiazole 1f wit nitroarenes, leading to ni
