Relevant academic research and scientific papers

Do upper limits to the multiple spiro acetalization of the cyclohexane ring exist?

An attempt to transform the pyranoside (5) into the bifaciai ligand (3) is described. The first subtarget is acetal (13) whose conversion into tris acetal (17) is made possible by remote C-H activation. Regrettably, triol (20) does not lend itself to comparable triple cyclization.

Two routes to enantiomerically pure 3-aminoinosose derivatives

Epoxidation with hydrogen peroxide/benzonitrile of (2S)-(2,4/3)-2,3,4-tribenzyloxycyclohex-5-enone ethylene acetal (13), obtained from methyl 2,3,4-tri-O-benzyl-6-deoxy-α-D-xylo-hex-5-enopyranoside (9), gave the (2,4/3,5,6)-5,6-anhydride 14 which, with so
