摘要：

A sweet disposition: Simple protocols for the synthesis of (1→1)- and (1→6)-linked C-disaccharides have been developed (see scheme). A one-pot Au-catalyzed alkynol cycloisomerization followed by BF3×Et 2O, Et3SiH reduction has been established as the key reaction for C-disaccharide synthesis including all possible pyran-pyran, furan-furan, and pyran-furan combinations. © 2013 WILEY-VCH Verlag GmbH & Co.
