Facile Synthesis of Carboxamide-Substituted 1,3,4-Thiadiazines and 5,6-Dihydro-4H-1,3,4-Thiadiazin-5-Ols

Chemistry of Heterocyclic Compounds, 2019
Novel 2-carboxamide-substituted 1,3,4-thiadiazines and 5,6-dihydro-4H-1,3,4-thiadiazin-5-ols were synthesized by the reaction of oxamic acid thiohydrazides with phenacyl bromides. This reaction was performed using an equimolar mixture of thiohydrazide and α-bromoacetophenones in methanol under basic conditions.

The chemistry of a 1,3,4-thiadiazin-6-one

Journal of the Chemical Society, Chemical Communications, 1981
2-Dimethylamino-5-phenyl-1,3,4-thiadiazin-6-one (2), the first representative of this ring system, undergoes thermal fragmentation to yield benzonitrile, dimethylcyanamide, and 2-dimethylamino-5-phenyl-1,3,4-thiadiazole; its reaction with 1-diethylamino-propyne results in a mixture of adducts, the 1H-pyridazin-4-one (7) and the 5H-pyridazin-4-one (10).

STEROIDAL 2-AMINO-1,3,4-THIADIAZINES AND AMINOTHIAZOLES

Phosphorus and Sulfur and the Related Elements, 1979
Abstract The reaction of 16-bromo-17-ketones and 2-bromo-3-ketones reacted readily-upon heating for short periods of time with thiosemicarbazide in isopropanol in a 1:2 ratio to give 2-amino-1,3,4-thiadiazines. Extension of this reaction to 21-bromo-33-hydroxy-5-pregnen-20-one produced the corresponding thiadiazine.
