4-Acyl-2-acylamino-4,5-dihydro-1,3,4-thiadiazoles by Acylation of Thiosemicarbazones
Andreae, Siegfried,Schmitz, Ernst,Seeboth, Helmuth
, p. 205 - 214 (2007/10/02)
Thiosemicarbazones and acid anhydrides or halides react to 4-acyl-2-acylamino-4,5-dihydro-1,3,4-thiadiazoles (2a-2v) in high yields. 3-Acyl-2-amino-4,5-dihydro-1,3,4-thiadiazoles 5 are proved as intermediates in this conversion.In special cases they can b
