Wittig reagent sugars

Barnes, J J, Davidson, A H, Hughes, L R, Procter, G, The synthesis of optically active tetrahydropyrans by the addition of a stabilized Wittig reagent to pyranose sugars, J. Chem. Soc., Chem. Commun., 1292—1294, 1985. [Pg.359]

Other examples have been given of the preparation of branched-chain and extended-chain alkenes by application of Wittig reagents to sugar aldehydes and ketones,and the mass spectra of alkenes derived from 1,2 5,6-di-O-iso-propylidene-D-r/Z o-hexos-3-ulose have been described.Compound (25) was... [Pg.113]

Free sugars themselves can undergo nucleophilic attack at the anomeric centre as in the synthesis of the ester (42) from the corresponding free sugar by means of a Wittig reagent,and related procedures must have been involved in the generation of compounds such as (43),and (45) by reactions of... [Pg.32]
