Abstract
The (6′S)-configuration of brevipolides A–J (1–10), isolated from Hyptis brevipes, was established by X-ray diffraction analysis of 9 in conjunction with Mosher’s ester analysis of the tetrahydro derivative 11 obtained from both geometric isomers 8 and 9 as well as by chemical correlations. The structure of the new brevipolide J (10) was characterized through NMR and MS data as having the same 6-heptyl-5,6-dihydro-2H-pyran-2-one framework...
