Abstract
The structures of the novel 10-membered lactones, named decarestrictines A1/A2 (1/2), B (3), C1/C2 (5/6) and D (7), are presented. The structures of these secondary metabolites, isolated from different Penicillium species, were established by spectroscopic analysis and confirmed by X-ray analysis of 7 and a derivative of 3 leading to the stereochemical information. The decarestrictines vary in the oxygenation pattern between C-3 and C-7 and show structural similarities to known lactones from other fungi.Keywords
