We herein report an efficient approach for the assembly of multiply substituted imidazoles and oxazoles in a single-step manner. These transformations are based on a decarboxylation addition and annulation of readily accessible aromatic carboxylic acids a

A practical and flexible intermolecular protocol for the diverse synthesis of trisubstituted oxazole derivatives via a Pd-catalyzed direct C-H addition of electronic-rich heteroarenes to O-acyl cyanohydrins bearing an α-hydrogen/cyclization sequence is described. A wide range of trisubstituted oxazoles can be prepared from readily available starting materials in good to high yields with high efficiency under redox neutral reaction conditions.

Cyanohydrin esters 1-31 have been prepared from α-ketonitriles and aldehydes using DABCO (1,4-diazabicyclooctane) as nucleophilic acylation catalyst.The modofied piperonal 8 was found to inhibit the formation of thromboxane synthetase.
