An efficient and robust protocol for the preparation of 3-substituted isocoumarins via palladium-catalyzed nucleophilic addition/oxidative annulation of bromoalkynes with benzoic acids has been developed. Remarkably, preliminary mechanistic studies indicated that the transformation might proceed via a stereo- and regioselective nucleophilic addition and C-H functionalization procedure.

3-Substituted isocoumarins 1-19 were synthesized and evaluated for their thymidine phosphorylase inhibitory activity. Eight (8) compounds exhibited a varying degree of inhibitory activity towards thymidine phosphorylase from E. coli with IC50 values between 61- 402 μM. The activities were compared with the standard 7-deazaxanthine (IC50 = 39.28 ± 0.76 μM).

We describe the first studies on the chemistry of 2-(2-oxo-3-phenylpropyl) benzaldehydes, which were converted into 3-benzylisochromen-1-ones via the corresponding 2-(2-oxo-3-phenylpropyl)benzoic acid. The 2-(2-oxo-3-phenylpropyl) benzaldehydes proved to be convenient starting materials for the synthesis of 3-phenyl-2-naphthols. Oxidation of the latter compounds resulted in a novel, efficient synthesis of 3-phenyl-1,2-naphthoquinones, which were efficiently transformed into 2-hydroxy-3-phenyl-1,4-naphthoquinones.

(dl)-3-Benzyl-3,4-dihydroisocoumarin 6, a model of Feralolide, has been synthesized through 3-benzylisocoumarin 2 which is prepared by the condensation of phenylacetyl chloride with homophthalic acid. Alkaline hydrolysis of 2 yielded the keto-acid 3 which
