7H-Triazolothiazin-7-ones by Deamination Cyclization of S-Acrylates of 4-Amino-3(3H)-1,2,4-triazolethiones
Heindel, Ned D.,Reid, Jack R.
, p. 2479 - 2482 (2007/10/02)
Condensation of 4-amino-3(3H)-1,2,4-triazolethiones with methyl propiolate gave S-acrylic esters.S-Acrylic acids prepared from these esters underwent a deamination cyclization of 7H-triazolothiazin-7-ones with the loss of the elements o
