Synthesis of vicenin-1 and 3, 6,8- and 8,6-di-C-beta-D-(glucopyranosyl-xylopyranosyl)-4',5,7-trihydroxyflavones using two direct C-glycosylations of naringenin and phloroacetophenone with unprotected D-glucose and D-xylose in aqueous solution as the key r
Vicenin-3 was synthesized from naringenin via a short five-step reaction, which included two regioselective direct C-glycosylations with d-glucose and d-xylose (yields: 22% and 30%, respectively) as the key reactions for a total yield of 4.4%. Vicenin-1 was also synthesized from phloroacetophenone via a 10-step reaction, including the same glycosylation described above, for a total yield of 2.7% with a vicenin-3 yield of 1.7%.

Dihydrostilbene derivatives from Glycyrrhiza glabra leaves.
Four new dihydrostilbenes, alpha,alpha'-dihydro-3,5-dihydroxy-4'-acetoxy-5'-isopentenylstilbene (1), alpha,alpha'-dihydro-3,3',4'-trihydroxy-5-O-isopentenyl-6-isopentenylstilbene (2), alpha,alpha'-dihydro-3,5,3'-trihydroxy-4'-methoxystilbene (3), and alpha,alpha'-dihydro-3,3'-dihydroxy-5beta-d-O-glucopyranosyloxy-4'-methoxystilbene (4), together with seven known flavonoids, glabranin isomer, naringenin, lupiwighteone, pinocembrin 7-O-glucoside, astragalin, isoquercitrin, vicenin II, and the inositol, pinitol, were isolated from the leaves of Glycyrrhiza glabra grown in Sicily. The structures of 1-4 were elucidated by spectroscopic methods.
