Starting with the α-D-erythro-hex-3-enopyranoside 1 the isomers with β-D-erythro as well as α- and β-D-threo configuration 5b, 3b, and 9 are prepared.In Mitsunobu reactions the 1,2-cis derivatives 1 and 9 smoothly undergo SN2-type substitutions
Syntheses of Biologically Important Carbohydrates, 25. On the Regioselectivity of the Sharpless Reaction; The vic. cis-Oxyamination of Unbranched and 3-C-Branched Ald-2- and Ald-3-enopyranosides
Schulte, Gerhard,Meyer, Wolfgang,Starkloff, Angelika,Dyong, Ingolf
, p. 1809 - 1821 (2007/10/02)
The configurations and the ratios of regioisomeric amino sugars obtained by vic. cis-oxyamination of unsaturated carbohydrates 1, 4, 9, 16, 19, 21 are determined.Due to the ratios of amino sugars from the ald-3-enopyranosides 9 and 16 it is obvious that t
