The chemical synthesis of beta-(1-->4)-linked D-mannobiose and D-mannotriose.
Twaddle, Gavin W,Yashunsky, Dmitry V,Nikolaev, Andrei V
, p. 623 - 628 (2007/10/03)
A D-cellobiose derivative was converted to D-mannobiose via simultaneous epimerization at C-2 and C-2'. Subsequent beta-D-glucosylation and epimerization at C-2" gave D-mannotriose.
