| 英文摘要 | To avoid tautomerism in the hydrolyzable tannins which lack an acyl group at the glucose C-1 position, a new method for the protection of the C-1 atom has been developed. That is reaction of the tannins with p-anisidine in the presence of acetic acid, followed by sodium cyanoborohydride reduction, afforded, without notable hydrolysis of ester bonds, the aminoalditol derivatives (1a-7a) in 50-80% yields. The proton and carbon-13 nuclear magnetic resonance (H-1- and C-13-NMR) spectra of these derivatives exhibited much simpler signal patterns typical of an open-chain form of glucose, and almost all the signals could be assigned. Application of this method to the structure elucidation of the new tannins, flosin A (22) and reginins A (23) and B (24), isolated from the leaves of Lagerstroemia flos-reginae RETZ. (Lythraceae), established their structures including the orientation of the 4,6-positioned valoneoyl group. In addition, the structure of a new hydrolyzable tannin, lagerstroemin (21), which was concomitantly isolated from the above species, was elucidated. |
