General description

3-Isochromanone has been reported to be isolated from the fungus Nigrospora sp. PSU-F12. An improved Knoevenagel condensation of 3-isochromanone with aromatic aldehydes has been achieved by microwave irradiation on solid supports in the presence of various catalysts. Synthesis of 3-isochromanone via Beayer-Villiger rearrangement has been reported.

Application

3-Isochromanone may be used as starting reagent in the synthesis of of BDPBI (7-bromo-1,4-dihydro-2-phenyl-4,4-bis(4-pyridinylmethyl)2H-isoquinolin-3-one dihydrochloride).

The pharmacological effects of BDPBI (7-bromo-1,4-dihydro-2-phenyl-4,4-bis(4-pyridinylmethyl)2H-isoquinolin-3-one dihydrochloride) were tested on isolated endothelium-containing or denuded aorta of the guinea pig. BDPBI with the formula C(27)H(24)BrCl(2)N(3)O was synthesized starting with 3-isochromanone. In the endothelium-containing preparations of the aortic rings, phenylephrine (PHE; 10
