Abstract

While the chemistry of thiopyrones have been widely investigated, little is known about the synthesis and chemical behavior of the isomeric thiopyran-3-one system. In the course of our study on the intramolecular cyclization of compounds containing heteroatoms, we are interested in thiopyran-3-ones1 and we have now developed st novel and versatile synthesis for 3, 6-dihydrothiopyran-3-ones bearing substituents on the ring. The ...
