Conversion of Dipyridazinothiazines into Dipyridazinopyrroles through a Base-Induced Extrusion of Sulfur

A novel ring contraction for the conversion of 2,7-disubstituted 10H-dipyridazinothiazine-1,6-(2H,7H)-diones (4'a-c) into the corresponding 2,6-disubstituted 9H-dipyridazinopyrrole-1,5(2H,6H)-diones (7'a-c), through a ba

CONCURRENT FORMATION OF TWO ISOMERIC DIPYRIDAZINO-THIAZINES ATTENDED WITH OCCURRENCE OF A UNIQUE DIPYRIDAZINO-PYRROLE

Interaction of 4-amino-5-mercapto-2-methyl-3(2H)-pyridazinone (1) and 4,5-dichloro-2-methyl-3(2H)-pyridazinone (3) in a basic medium, followed by benzylation, yielded concurrently 10-benzyl-2,7-dimethyl-dipyridazinothiazine-1,6(2H,7H)-
