This study involves the total synthesis of casuarinin, a naturally occurring ellagitannin, in which an open-chain glucose is esterified with two (S)-hexahydroxydiphenoyl (HHDP) groups. One HHDP group incorporates a C-glycosidic bond between its benzene ring and the glucose moiety, which was constructed with complete stereoselectivity using a benzyl oxime group that opened the glucopyranose ring and acted as a scaffold for C-glycoside production. This total synthesis enables future structure-activity relationship studies of this compound.

Key Word Index - Liquidambar formosana; Hamamelidaceae; tannin; hydrolysable tannin; ellagitannin; liquidambin; equilibration; biogenesis; casuarinin; pedunculagin. A new ellagitannin, named liquidambin, which could be biogenetically closely correlated with casuarinin and pedunculagin, has been isolated from the leaves of Liquidambar formosana.Its structure was determined as 5-O-galloyl-2,3,4,6-di-O-(S)-hexahydroxydiphenoyl-D-glucose.The structural equilibration due to hydration of the aldehyde group of the glucose core in this tannin was shown from its (1)H and (13)C NMR spectra.
