Five new resin-glycosides, named merremosides a (1), b (2), c (3), d (4), and e (5), were isolated from the tuber of Merremia mammosa (LOUR.) HALLIER f. (Convolvulaceae), an Indonesian medicinal plant. The structures of 1, 2, 3, 4, and 5 have been elucidated on the basis of chemical and physicochemical evidence, including syntheses of (11S)-(+)- and (11R)-(-)- jalapinolic acid (16b and 18b) and the glycosidic acid designated as merremoside i (6).

(11S)-(+)-Jalapinolic acid (11a) and (11R)-(-)-jalapinolic acid (13a) have been synthesized from cyclododecanone (2) via Sharpless asymmetric epoxydation of an allylic alcohol (6).Since synthetic (11S)-(+)-jalapinolic acid (11a) and natural jalapinolic ac
