Practical synthesis of 2-deoxy sugars via metal free deiodination reactions

2-Deoxy-glycosides, in which the C-2 hydroxyl group is replaced with a hydrogen atom, are important motifs in numerous bioactive natural products and pharmaceutical molecules. Herein, an improved dilauroyl peroxide-mediated radical deiodination reaction b

An efficient method for the synthesis of pyranoid glycals

A simple and efficient procedure was designed for the preparation of pyranoid glycals. In a novel fashion, a series of protected glycopyranosyl bromides underwent reductive elimination in the presence of zinc dust and ammonium chloride in CH3CN at 30-60 °C. The corresponding glycals were obtained with excellent isolated yields (72-96%) in a short time (20-50 min). Furthermore, the transformation was compatible with different protection patterns and conveniently scalable (86% for 45 g acetobromoglucose) which made it very applicable in organic synthesis.

A mild and environmentally benign method for the synthesis of glycals in PEG-600/H2O

Glycals were synthesized via a simple, mild, convenient and environmentally benign procedure, in which protected glycosyl bromides undergo the reductive elimination in the presence of zinc in PEG-600/H2O at room temperature. The glycals were obtained in 75-92% isolated yields.
