A facile, efficient and environmentally friendly methodology for the preparation of phenolic esters is realized via metal-free coupling of carboxylic acids and arylboronic acids. This sequential one pot reaction, employing methyl propiolate as an activating reagent, proceeds through the formation of enol ester intermediate, followed by a nucleophilic attack on the C-O bond under the oxidation of hydrogen peroxide. These studies display that enol esters, despite previously being overlooked as synthetic intermediates, would be the valuable building blocks for developing carbon–carbon and carbon–heteroatom bond-forming reactions.

We investigated the stereoselective coupling of thymine with sulfoxides derived from mesothiolane-3,4-diol via the Puremeter reaction. The introduction of 2,4-dimethoxybenzoyl groups to the hydroxyl groups of meso- thiolane-3,4-diol-1-oxide was effective
