Pyridinium-1-thioacylaminides

Pyridinium-, 2-methylpyridinium-, and 2,6-dimethylpyridinium-1-thioacylaminides (5-7) were prepared from the corresponding unsubstituted pyridinium-1-aminides and methyl dithiocarboxylates in fairly good yields.The alkylation reaction of 5-7 took place ex

Preparation of New Nitrogen-Bridged Heterocycles. XIV. Further Investigation of the Desulfurization and the Rearrangement of Pyrido-1,3,4-thiadiazine Intermediates

The formation of pyrazolopyridine derivatives via the desulfurization and the rearrangement of pyrido-1,3,4-thiadiazine intermediates having various substituents at the 2- and 4-positions was investigated, and the wide applicability of this
