摘要：

A series of 1,3-thiazines has been synthesized by the reactions of N-aroylsubstituted thioureas with ethyl propiolate, dimethyl but-2-ynedioate and (E)-1,4-diphenyl-but-2-ene-1,4-dione. The reaction of antipyrinylphenyl thiourea with at-deficient acetylenic reagents did not afford the corresponding 1,3-thiazines, whereas pyrrolo-pyrazolopyrimidines were obtained.
