A simple and practical route for the asymmetric synthesis of (S)-4-(4-fluorophenyl)-1,4,5,6-tetrahydro-6oxo-3-pyridinecarboxylic acid (1) is presented. The procedure comprises catalytic desymmetrization of a meso-anhydride using a chiral thiourea organocatalyst, followed by selective formylation and
Acyl chlorides are split into acyl and chlorine radicals by light of wavelength 254 my. Since the dissociation energy of the chlorine-hydrogen bond is considerably larger than that of the acyl-hydrogen bond, substitution of the substrate by acyl radicals is observed on irradiation of acid chlorides.
