TOTAL SYNTHESIS OF (+/-)-ISOALANTOLACTONE AND (+/-)-DIHYDROCALLITRISIN

Two eudesmanolides having opposite stereochemistry of lactone ring each other, (+/-)-isoalantolactone and (+/-)-dihydrocallitrisin were sythesized stereoselectively by a route involving alkylation of 2-methyl-3-furonic acid and oxidation of furan ring.

Total Synthesis of Three Eudesman-12,8-olides, (+/-)-Isoalantolactone, (+/-)-Dihydrocallitrisin and (+/-)-Septuplinolide; Structure Revision of Septuplinolide

Four eudesman-12,8-olides, (+/-)-isoalantolactone, (+/-)-dihydrocallitrisin, (+/-)-septuplinolide and its epimeric eudesmanolide at C-4 were synthesized stereoselectively via the route involving alkylation annulation of 2-methyl-3-furoic acid and oxidation of the furan ring.It was found that the structure of septuplinolide is the C-4 epimer of the reported structure.
