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