| —— | methyl-[4,6-dichloro-bis-O-(toluene-4-sulfonyl)-4,6-dideoxy-α-D-galactopyranoside] | 20550-17-8 | C21H24Cl2O8S2 | 539.455 |
The structures of methyl 4,6-dichloro-4,6-dideoxy-α-D-hexoside and methyl "4-chloro-4-deoxy-β-pentoside" (I) have been investigated. The desulphation reaction leading to the formation of the latter compound is described. Replacement of the hydroxyl group at C(4) by a chlorine atom in both compounds is shown to have occurred with inversion of configuration.
