title: Cyclopentene dialdehydes from Tabebuia impetiginosa.
abstract: The isolation of two cyclopentene dialdehydes, 2-formyl-5-(4'-methoxybenzoyloxy)-3-methyl-2-cyclopentene-1-acetal dehyde, and 2-formyl-5-(3', 4'-dimethoxybenzoyloxy)-3-methyl-2-cyclopentene-1-acetaldehyde, from the bark of Tabebuia impetiginosa is reported. The structures were established by analysis of spectroscopic data. These compounds showed anti-inflammatory activity.
