โœฆ Synopsis


The tetrasaccharide 5-aminopentyl glycoside ฮฒ-D-Manp-O-benzylidene-1-thio-ฮฒ-D-glucopyranoside (1) and ethyl 2,3,4-tri-O-benzyl-1-thio-ฮฑ-D-mannopyranoside (5) in 5 (1วž4)-ฮฒ-D-Glcp-(1วž4)-ฮฑ-L-Rhap-(1วž3)-ฮฒ-D-Glcp-1-O-(CH 2 ) 5 NH 2 (22 ) r el at ed to th e e xo po ly sa cc ha ri de of steps. Building block 20 was obtained by coupling N-Zprotected 5-aminopentyl 2-O-benzyl-4,6-O-benzylidene-ฮฒ-Arthrobacter sp. CE-17 was synthesized by coupling of the properly protected disaccharide blocks ฮฒ
