Synthesis and heterocyclization of 3-aryl-2-methyl-2-thiocyanatopropanamides
摘要:
Reactions of arenediazonium tetrafluoroborates with methacrylamide in the presence of potassium thiocyanate in aqueous acetone (1: 2.5) or aqueous dimethyl sulfoxide (1: 4) gave the corresponding 3-aryl-2-methyl-2-thiocyanatopropanamides which underwent heterocyclization in boiling acetic anhydride to produce difficultly accessible 2-(acetyl)amino-5-benzylthiazol-4(5H)-ones.
