109. Oligosaccharide analogues of polysaccharides: Part 8. Orthogonally protected cellobiose-derived dialkynes. A convenient method for the regioselective bromo- and protodegermylation of trimethylgermyl- and trimethylsilyl-protected dialkynes

The cellobiose-derived dialkynes 14 and 15 were prepared by glycosidation of the acceptor 9 with the thioglycosides 12 (82%) and 13 (85%), respectively. The acceptor 9 was prepared from the known alcohol 2 via the lactone 7 in five steps (48% overall), an
