Highly (Z)-diastereoselective approaches for the synthesis of trifluoromethylated exo-glycals by copper and photoredox catalysis are described. These complementary reactions are applicable to a wide range of methylene exo-glycals generated from the corresponding pyranoses and furanoses and give trifluoromethylated compounds under mild conditions in moderate to good yields. DFT calculations have allowed a rationalization of the observed (Z)-stereoselectivity.
Gold-catalysed glycosylation reaction using an easily accessible leaving group

, p. 5094 - 5097 (2015/05/13)
Gold(iii)-catalysed glycosylation reaction has been developed by employing a new and easily accessible leaving group synthesized from ethyl cyanoacetate. Several nucleophiles like alcohols, thiols, allyltrimethylsilane, trimethylsilyl azide and triethylsilane have been reacted to make the corresponding glycosides in good yields and with marginal to excellent α-selectivity.

We report the crystal structures of two galactosylacetylenes: 3,7-anhydro-4,5,6,8-tetra-O-benzyl-1,1,2,2-tetradehydro-1,2-dideoxy-1-C- (trimethylsilyl)-D-glycero-L-mann ooctitol (7) and 3,7-anhydro-4,5,6,8-tetra-O- benzyl-1,1,2,2-tetradehydro-1,2-D-glycero-L-mannooctitol (8). A short overview of the synthetic chemistry used to obtain these targets is mentioned. Copyright Taylor & Francis Group, LLC.
