✦ Synopsis

The t i t l e trisaccharide has been synthesized containing a 3-deuterated central mannopyranosyl unit and 2,3,4,6,6'-pentadeuterio mannopyranosyl units i n both arms. 2-Propyl 2-0-benzyl-4,6-0-benzylidene-3-deuterlo- -I)-D-mannopyranoside was obtained by stereoselective deuteride reduction of the corresponding 3-0x0 derivative and was reacted with 2,3,4,6,6'-pentadeuterio-oc-D-mannopyranosyl bromide. The disaccharide obtained was glycosylated with another equivalent of the same bromide after hydrolysis of the benzylidene group.
