High-throughput preparation of alkyl 4-aryl substituted-2-methyl-6-thioxo- 1,4,5,6-tetrahydropyridine-3-carboxylates under microwave irradiation

Abstract

An efficient high-throughput synthesis of 4-aryl substituted 1,4,5,6-tetrahydro-2-methyl-6-thioxopyridine-3-carboxylates 5a-p was developed by using Lawesson's reagent, a very effective thionating reagent for carbonyl compounds, under conventional conditions and microwave irradiation. In order to gain a better understanding of the structure of the heterocycles obtained, theoretical calculations at the ab initio level were carried out. © ARKAT-USA, Inc.
