  Microwave-Assisted, One-Pot Synthesis of 5-Thia-4b,10-diaza-indeno[2,1-a]-indene-5,5-dioxide and 10H-11-Thia-5,10a-diaza-benzo[b]fluorene-11,11-dioxide

  摘要：

  The one-pot, microwave-assisted synthesis of 5-thia-4b,10-diaza-indeno[2,1-a]indene-5,5-dioxide (6) and 10H-11-thia-5,10a-diaza-benzo[b]fluorene-11,11-dioxide (7) from 1,2-phenylenediamine and 2-aminobenzylamine, respectively, is described. Generation of a sulfonamide through reaction of the appropriate diamine with 2-cyanobenzenesulfonyl chloride is followed by a multistep intramolecular transformation and subsequent elimination of ammonia to provide the corresponding tetracycle in good yield.
