N-Allyloxycarbonyl derivatives of D-glucosamine as promotors of 1,2-trans-glucosylation in Koenigs-Knorr reactions and in Lewis acid catalysed condensations

Boullanger, Paul,Banoub, Joseph,Descotes, Gerard

, p. 1343 - 1348 (2007/10/02)

The use of suitably blocked D-glucosamine derivatives possessing the N-allyloxyxarbonyl protective group of the amino function represents potential new routes to 1,2-trans-glucosylations.Both 3,4,6-tri-O-acetyl-2-N-allyloxycarbonyl-2-amino-2-deoxy-α-D-glu
