Abstract
Calyxolanes A (1) and B (2) are rare 1,3-diphenylbutanoid compounds isolated from the marine sponge Calyx podatypa collected in Puerto Rico. Their structures, including relative stereochemistry, have been determined by spectroscopic methods. The unique 2,4-diphenyloxolane function in 1 and 2 was established by 2D 1H-1H and 1H-13C NMR correlation experiments and confirmed by mass spectral analysis. A suggestion is made as to their biogenetic origin.Entities:
