Synthesis of kanamycin A analogs containing 6-amino-3-oxa-2,3,4,6-tetradeoxy-D- and -L-glycero-hexopyranose

Kuwahara, Ryuji,Tsuchiya, Tsutomu

, p. 107 - 122 (2007/10/03)

6-Azido-3-oxa-2,3,4,6-tetradeoxy-D- and -L-glycero-hexopyranoses were synthesized in five steps from (2S)- and (2R)-1,2-O-isopropylideneglycerols, respectively. After conversion into the corresponding ethyl 1-thioglycosides, each was condensed with a protected derivative of 6-O-(3-amino-3-deoxy-α-D-glucopyranosyl)-2-deoxystreptamine (16). Deprotection and reduction of the azido group of the condensation products gave the title compounds.
