Abstract
Five new furanocembrenoids (3-7) were isolated from the Dufour gland secret ion of the Brazilian ant Crematogaster brevispinosa ampla. The structure of the major component was established by a detailed high-field 1D and 2D NMR study as the dibutanoate 3. Compounds 4 and 5 were shown to be the two iso meric monoacetate monobutanoates corresponding to 3, whereas 6 and 7 are th e two isomeric monohydroxy monobutanoates.
