SYNTHESIS OF SOME 5H-PYRANO- AND 5H-PYRIDO<2',3':4,5>PYRIDO<2,1-b>BENZOTHIAZOL-5-ONE DERIVATIVES
The addition reactions of 3-hydroxy-1H-pyrido<2,1-b>benzothiazol-1-one, 1, have been investigated.Thus, 1 added to aryl isocyanates to give the 2-carbamoyl derivatives 2a,b and to activated alkenes to give the 2-alkylated derivatives 5a-c.Compound 1 reacted also with alpha-substituted cinnamonitriles, 6a-l, to give different products 7, 12, 13 and 15 according to the nature of the substituent in 6.Compounds with the ring systems pyrido<2',3':4,5>pyrido<2,1-b>benzothiazole and pyrano<2',3':4,5>pyrido<2,1-b>benzothiazole have been obtained.The first ring system is a new one.
