Insight Into

The structure of the decalone previously reported from the oxidation of guaiol has, after X-ray crystallographic analysis, been revised to structure (3c) which contains a cis -fused ring system. Deuteration studies give insight into the conformation of the transition state during the reaction.

AbstractNew potential transition state analogue inhibitors for N-acetylglucosyltransferases (GnTs) were synthesised. These compounds based on psico- and tagatofuranose (structure) scaffold contained a 2-thiophenyl-1-O-diethylphosphate moiety mimicking the proposed model of the transition state of the enzymatic reaction catalysed by N-acetylglucosyltransferases. The synthesised compounds as well as their precursors were fully characterised by NMR, optical rotation and mass techniques. Anomeric configuration of tagatofuranose derivatives was confirmed by X-ray crystallography. Two types of potential human glycosyltransferase (GnTs) inhibitors representing donor UDP-GlcNAc, assigned for biological assays on human GnTs, were prepared.
