Abstract: The chemical structure of linear dihydropyranocoumarins Pd-C-I was studied in detail by COLOC spectrum as well as 1H-1H COSY spectrum.It was observed that the attached position of acyl group of Pd-C-I can be determined by correlated cross peaks in COLOC spectrum.The result shows the significance on structural studies and discussion of structure activities relationship of linear dihydropyranocoumarins.The mistakes in the literatures about the assignments of some signals of carbons and protons were also revised.
Key words: Pd-C-I, Linear dihydropyranocoumarins, COLOC spectrum, Attached position of acyl group
