The reaction of N,N '‐dimethyl‐2‐nitroethene‐1,1‐diamine (8) with α,ß‐unsaturated acyl isothiocyanates 9 affords 3,3‐diamino‐2‐nitroacrylthioamides 10 ( Scheme 2 ) in moderate‐to‐good yields. Cyclization of 10 under acidic conditions gives 1,3‐thiazin‐4‐one derivatives of type 11 . Oxidative cyclization of 10 with diethyl azodicaboxylate leads to 4‐nitro‐1,2‐thiazol‐5(2 H )‐imine derivatives 12 .
