Abstract
4-Amino and 5-aminobenzothiadiazoles were prepared and submitted to reaction with activated enolethers to prepare N-substituted benzothiadiazolylaminoethylene derivatives. Selected aminoethylenes were thermally cyclized to angularly annelated thiadiazolylaminoethylene under Gould–Jacobs reaction conditions. Prepared products were modified to obtain variously substituted thiadiazoloquinolones.
