NEW 2-HYDRAZONOPHENYLTHIOACETAMIDES INTERMEDIATES IN THE SYNTHESIS OF 6-ACYLAMINO-3,6- DIHYDRO-2H-1,3,4-THIADIAZINES
摘要:
The three steps synthesis of new 2-hydrazonophenylthioacetamides having a N-monosubstitued thioamide group is described. The selective acylation of the thioamide nitrogen atom involves an intramolecular cyclisation affording 3,6-dihydro-2H-1,3,4-thiadiazines with good yields.
