摘要：

The stereochemical structures of two alpha-pyrones previously isolated from Cryptocarya lntifolia have been shown to be 6R-[2R,4S,6S-(triacetoxy)-heptyl]-5,6-dihydro-2H-pyran-2-one and 6R-[2S,4S-(diacetoxy)-pentyl]-5,6-dihydro-2H-pyran-2-one. Syndenolide from Syncolostemon densiflorus is 6R-[5S-(acetoxy)1R,2R,3S-(trihydroxy)-heptyl]-5,6-dihydro-2H-pyran-2-one. Copyright (C) 1997 Elsevier Science Ltd.
