5,6-Dihydro-α-pyrones and two bicyclic tetrahydro-α-pyrone derivatives from Cryptocarya latifolia

Abstract Two new 6-substituted-5,6-dihydro-α-pyrones have been isolated from the bark Cryptocarya latifolia. In addition two new, closely related dioxabicyclo [3,3,1]nonan-2-one derivatives, have been obtained in lower concentration from the same plant source.
