TL;DR: In this article, a 1,4-addition of hydrazoic acid to a corresponding hex-2-enopyranose was used to synthesize a 4-O(2,6-dideoxy)-α-L-arabinopyranosyl analogue.
Abstract: The methyl 4-O-(2,6-dideoxy-2-iodo-α-L-mannopyranosyl)-α-L-acosaminide (11) and the methyl 4-O-(2,6-dideoxy-α-L-arabinopyranosyl)-α-L-acosaminide analogue (12) have been stereoselectively synthesized in seven and eight steps, respectively, from di-O-acetyl-L-rhamnal (4) and methyl 2,3,6-trideoxy-α-L-erythro-hex-2-enopyranoside (5); the key step involved a 1,4-addition of hydrazoic acid to a corresponding hex-2-enopyranose.
