5‐Arylmethylene‐2‐disubstituted amino‐4‐oxo‐2‐thiazolines 1a‐d reacted with six and two moles of sodium methoxide to give the 2‐mercaptocinnamic acid esters 6 and mixtures of 2,2 ‐dimethoxy‐4‐oxothiazolidines 4 and 2,4‐dioxothiazolidines 5 , respectively. The intermediate mixture of the sodium salt of 5‐aryImethylene‐2,2‐dimethoxy‐4‐oxothiazolidines 3 in the above mentioned transofrmations was established. The structures of 3, 4, 5 and 6 were based on analytical and spectral evidence. The route of conversion of 1 into 3, 4,5 and 6 was presented and discussed.
