Reaction of 4‐phenylthiosemicarbazide with dialkyl acetylenedicarboxylate in CH 2 Cl 2 at 0°C lead to construction of alkyl 3‐amino‐2‐phenyliminothiazolidine‐4‐one‐5‐ylidene acetate in a few minutes and good yields. Alternatively, the use of thiosemicarbazide has given the corresponding 3‐amino‐2‐iminothiazolidine‐4‐one‐5‐ylidene acetate, while application of di‐ t ‐butylacetylenedicarboxylate in these reactions has not entailed with cyclization.
