A Novel Synthesis of a Branched-chain Amino Sugar, Methyl 2-Amino-2,3-dideoxy-3-C-formyl-α-D-xylofuranoside-3'R,5-hemiacetal

Tatsuta, Kuniaki,Miyashita, Satoru,Akimoto, Kohji,Kinoshita, Mitsuhiro

, p. 3254 - 3256 (1982)

Methyl 2-amino-2N,3O-(o-benzenedisulfonyl)-2-deoxy-α-D-glucopyranoside, which was prepared from methyl 2-amino-2-deoxy-α-D-glucopyranoside and o-benzenedisulfonyl dichloride, was treated with sodium methoxide to afford exclusively a branched-chain amino sugar, methyl 2,3-dideoxy-3-C-formyl-2-(o-sulfobenzenesulfonyl)amino-α-D-xylofuranoside-3'R,5-hemiacetal sodium salt (6).Some derivatives were synthesized from 6.
