Abstract
(+)-Marmelo Lactones A (VA) and B (VB) were synthesized from erythro-γ-methyl-L-glutamic acid (IA) and threo acid (IB), respectively. The absolute configurations of natural marmelo lactones were thus determined to be (2R, 4S) for (+)-marmelo lactone A and (2R, 4R) for (-)-marmelo lactone B.Keywords
