• General Description: 2,3,4,6-Tetra-O-benzyl-D-glucono-1,5-lactone is a protected sugar derivative used as a key intermediate in carbohydrate chemistry, particularly in the synthesis of glycopyranosylidene 1,1-diazides. It serves as a precursor for reactions under phase-transfer catalysis (PTC) conditions, offering improved efficiency and yield compared to alternative methods. Its reactivity is notable in the synthesis of D-gluco diazides, where it demonstrates higher reactivity than analogous D-galacto or D-manno derivatives.

Synthesis of protected glycopyranosylidene 1,1-diazides

10.1055/s-1996-4264

This research outlines the synthesis of protected glycopyranosylidene 1,1-diazides, which are important intermediates in carbohydrate chemistry. The study aimed to develop efficient, safe, and improved methods for preparing these compounds from acetylated sugar dihalides or tetrabenzyl D-glucono-1,5-lactone. The researchers concluded that the use of phase-transfer catalysis (PTC) conditions was more effective than using sodium azide in DMSO for halogen substitution, leading to fair to excellent yields of D-gluco and D-galacto diazides. They also found that the reactivity of the substrates decreased in the order D-gluco > D-galacto > D-manno.
