Abstract

β-Oxodithioesters 1, sulfur analogues of β-ketoesters, are important synthons frequently used for the synthesis of heterocycles. 1 can easily be synthesized by the reaction of methyl ketones (or active methylene compounds) with dialkyl-, allyl-, or benzyl trithiocarbonates in the presence of NaH (Scheme [1]).[1] These versatile reagents are yellow and have a low melting point as well as an offensive odor.
