Manach, Claire Le,Baron, Aurélie,Guillot, Régis,Vauzeilles, Boris,Beau, Jean-Marie
scheme or table, p. 1462 - 1465 (2011/06/10)
A library of paclitaxel (taxol) mimics was obtained by a straightforward strategy involving rational design and an efficient synthesis of a simplified taxane core substitute, together with a click-chemistry combinatorial search for phenylisoserine side-chain surrogates.

Three new flavonoid glycosides, demethoxycentaureidin 7-O- β-D-galacturonopyranoside, pectolinarigenin 7-O- α-L-rhamnopyranosyl- (1?→4″)- β-D-glucopyranoside and 7-O- α-L-rhamnopyranosyl-(1?→4″)- β-D- glucuronopyranoside, a new megastigmane glucoside, byzantionoside B 6′-O-sulfate, and a new (Z)-hex-3-en-1-ol O-β-D-xylopyranosyl- (1″→2′)- β-D-glucopyranoside, were isolated from leaves of Ruellia patula JACQ., together with 12 known compounds, β-sitosterol glucoside, vanilloside, bioside (decaffeoyl verbascoside), acteoside (verbascoside), syringin, benzyl alcohol O- β-D-xylopyranosyl- (1″→2′)- β-D-glucopyranoside, cistanoside E, roseoside, phenethyl alcohol O- β-D-xylopyranosyl-(1″→2′)- β-D-glucopyranoside, (+)-lyoniresinol 3 α-O- β-D- glucopyranoside, isoacteoside and 3,4,5-trimethoxyphenol O- α-L- rhamnopyranosyl-(1″→6′)- β-D-glucopyranoside. Their structures were elucidated by means of spectroscopic analyses.
Large scale synthesis of the acetonides of l-glucuronolactone and of l-glucose: easy access to l-sugar chirons
Weymouth-Wilson, Alexander C.,Clarkson, Robert A.,Jones, Nigel A.,Best, Daniel,Wilson, Francis X.,Pino-González, Maria-Soledad,Fleet, George W.J.
experimental part, p. 6307 - 6310 (2010/01/18)
1,2-O-Isopropylidene-α-l-glucurono-3,6-lactone may be synthesized on a 100-200 g scale from cheaply available d-glucoheptonolactone in an overall yield of 94% in four steps via l-glucuronolactone. Subsequent elaboration to l-glucose, diacetone-l-glucose (1,2:5,6-di-O-isopropylidene-α-l-glucofuranose), and monoacetone-l-glucose (1,2-O-isopropylidene-α-l-glucofuranose) allows easy access to a range of l-sugar chirons.
