Abstract
The reaction of tri-O-benzyl-2-deoxyglucosylcopper(I) reagents with (η5-cyclopentadienyl)(5-methyl-2,3,4-η-hex-3-en-2-yl)(carbonyl)(nitrosyl)molybdenum tetrafluoroborate complexes derived from homochiral allylic acetates occurs with high regiocontrol and enantiofacial control to give C-glycosides. An electronic effect attributed to the nitrosyl ligand which normally governs the regiochemistry of the alkylation has been subverted.Keywords
