Showing papers on "Koenigs–Knorr reaction published in 1971"

TL;DR: In this paper, the Koenigs-Knorr condensation of the bromide with benzyl 2-acetamido-3,4-di-O -acetyl-2-deoxy-α-D -glucopyranoside and removal of protecting groups afforded 2.3.4.tri-O(tri- O -benzyl-α,β-L -fucopyrusyl- D-glucose 65% yield, the product containing a 7:3 ratio of α to β anomers.

TL;DR: Two α-D -linked disaccharides, 6-O -α-D-glucopyranosyl- D -galactose and 3-O-α- D-GLU-D −Galactose, were synthesized by reaction of 2- O -benzyl-3,4,6-tri-O − p -nitrobenzoyl-α(or β- D −glucophyranosy bromide with 1,2:3, 4-di- O −isopropyl
