Reaction of Diethyl Esters of 1-Acylamino-2,2-dichlorovinylphosphonic Acids and Their Analogs with the Lawesson's Reagent

摘要

Diethyl esters of 1-acylamino-2,2-dichlorovinylphosphonic acids and their analogs upon heating with the Lawesson's reagent are converted into the earlier unknown substituted 1,3-thiazol-4-ylthiophos-phonates in high yields.
