Abstract: | It has been established that iodocyclization of 3-(2-methyl-2-propenyl)thio-4-methyl-1,2,4-triazole occurs regioselectively
with annelation of the thiazole ring, 3-(3-methyl-2-butenyl)thio-4-methyl-1,2,4-thiazole with annelation of the thiazine ring,
and 3-allylthio-4-methyl-1,2,4-triazole with annelation of both rings to form derivatives of 1,3]thiazolo3,2-b]1,2,4]triazolium and 1,2,4]triazole5,1-b]1,3]thiazinium iodides. |
