## Abstract LโGlucose derivatives are prepared by two different routes. The first involves a modification of the previously reported multiโstep approach by __Shiozaki__^8^, starting from a Dโglucuronoโ1,5โlactone derivative, resulting in the isolation of 2,3,4,6โtetraโ__O__โbenzylโLโglucopyranose.
An inexpensive d-galactose was converted into l-ribose and its derivatives via mild reaction conditions. The l-ribosyl donor was submitted to a glycosidation according to Vorbrรผggen's conditions to give l-ribosides in high yields.
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
