TOTAL SYNTHESIS OF (+/-)-ISOALANTOLACTONE AND (+/-)-DIHYDROCALLITRISIN
Tada, Masahiro
, p. 441 - 444 (1982)
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.
