摘要：

A new 6-substituted-5,6-dihydro-alpha-pyrone (cryptofolione) has been isolated from the bark of two species of Cryptocarya. Its structure was elucidated by NMR techniques and chemical conversions. The relative stereochemistry at the two carbons bearing the hydroxyl groups was deduced after transformation into the corresponding acetonide derivative.
