Practical stereoselective synthesis of α-linked C-glucosamine propionic acid esters: conversion to GLA-60 derivatives Original Research Article

Radical C-glycosylation of glucosamine derivatives by acrylic acid esters gave the corresponding 3-(α-C-glucosyl)-propionate derivatives in moderate yields. One of them was used as a versatile synthon for GLA-60 derivatives. However, the biological activity of these compounds as LPS-antagonists was disappointing.
