Abstract

This chapter is an update to the earlier Science of Synthesis contribution (Section 14.4.4) describing methods for the synthesis of 4H-1-benzopyran-4-thiones. It focuses on the literature published in the period 2004—2018. All methods covered involve the thionation (replacement of the oxygen of a carbonyl group by sulfur) of the corresponding 4H-1-benzopyran-4-ones, either isolated or generated in situ.

Key words

4H-1-benzopyran-4-thiones - 4H-chromene-4-thiones - 4H-1-benzopyran-4-ones - thionation - Lawesson’s reagent - phosphorus pentasulfide - thiophosphoryl chloride
