Synthesis of functionalized imidazo[4,5-<i>e</i>]thiazolo[3,2-<i>b</i>]triazines by condensation of imidazo[4,5-<i>e</i>]triazinethiones with DMAD or DEAD and rearrangement to imidazo[4,5-<i>e</i>]thiazolo[2,3-<i>c</i>]triazines

Two series of functionalized imidazothiazolotriazine derivatives were synthesized via the condensation of imidazo[4,5-<i>e</i>]-1,2,4-triazine-3-thiones with acetylenedicarboxylic acid dimethyl and diethyl esters (DMAD and DEAD) and subsequent base-catalyzed rearrangement of the obtained...
