Synthesis of galactofuranose-containing disaccharides using thioimidoyl-type donors

Ronan Euzen

Four galactofuranose-containing disaccharides have been prepared utilising various thioimidates [Galf-SC(NR)XR′] and suitably protected acceptors as key precursors. We observed that the efficiency of the coupling reactions was particularly dependent on the ...

C(1 -> 4)-linked disaccharides through carbonylative Stille cross-coupling

Pierre Vogel, Peter Steunenberg

A tinglucal tributyl[4,6-O-bis(t-butyl)silylidene-3-O-tris(isopropyl)silyl]tin 7 and a triflate derived from isolevoglucosenone (1R,4R,5R)-4-benzyloxy-6,8-dioxabicyclo[3.2.1]oct-2-en-2-yl trifluoromethanesulfonate 10 undergo the carbonylative Stille conden ...

Synthesis of C-glycosides and C-linked disaccharides through carbonylative Stille coupling reactions

Peter Steunenberg

In the first part, we described the synthesis of C-(1'→1) and C-(1'→4) disaccharide precursors, which are readily obtained via the carbonylative Stille coupling of glucal and isolevoglucosenone derivatives. Tin glycals and triflates, derived from isolevogl ...
