  Synthesis of Carboxylactones and New Heterocyclic Compounds

  摘要：

  The Michael reaction of 2-ethoxycarbonyl-4-alkoxymethylbutanolides with methyl acrylate affords esterolactones in high yields. Alkaline hydrolysis of the latter resulted in carboxylactones that were transformed into ethyl alpha-bromolactonoesters. The reactions of the latter with thiourea and arylthioureas result in heterocyclic compounds of an original structure joint with a butanolide ring.
