Abstract

The rare and expensive D‐talose was conveniently synthesized from readily available D‐galactose in four steps with an overall yield of 58%. The key step was the inversion of equatorial 2‐OH of galactose to the axial one by S~N~2 reaction under the modified Lattrell‐Dax reaction conditions.

Two new photoaffinity reagents having photoreactive groups attached to C-6 of D-galactose have been prepared. 6-N-(6Azido-2-hydroxybenzoyl)-D-glucopyranosylamine and 6-N-(4-azido-2-hydroxybenzoyl)-D-galactopyranosylamine were synthesized by acylation of the protected amino sugars with 4-azidosalicoy
