The thiazole N-oxides are a poorly studied class of compounds. 2-Aminothiazole 3-oxides can be obtained by reductive cyclization of o-thiocyanatonitrobenzene [1], and also by reaction of α-chloroximes with barium thiocyanate [2]. At the same time thiocyanation of aromatic amines is widely used in the synthesis of fused 2-aminothiazoles. Thiocyanation of heterocyclic amines is usually carried out with thiocyanogen formed in situ by treating a ...
