Highly diastereoselective 1,4-addition of an organocuprate to methyl α-D-gluco-, α-D-manno-, or α-D-galactopyranosides tethering an α,β-unsaturated ester. Novel asymmetric access to β-C-substituted butanoic acids

The 1,4-addition of magnesium divinylcuprate prepared from vinylmagnesium bromide and cuprous bromide to some 4-O-crotonyl derivatives of methyl α-D-glucopyranoside proceeds with a high level of diastereochemical induction, providing the adduct in good-to

Stereochemistry of reduction of the diastereomerically pure N-tosyl 2-benzoyl-1,3-oxazines prepared from D-glucose was investigated with various reducing agents. It was found that the stereachemical outcome is consistent with the Cram's chelation model where the ring oxygen atom is involved in chelation, not the tosyl oxygen as in the 5-membered oxazolidines.
