STEREOSELETIVITIES IN THE REACTIONS OF α-D-HEXOPYRANOSID-4-ULOSES WITH DIAZOMETHANE

The stetreoselectivities in the reactions of diazomethane with various α-D-hexopyranosid-4-uloses are compared with those in Grignard reactions.The results support the hypothesis that the stereoselectivity of the diazomethane reaction is mainly controlled

Branched-chain Sugars. XXIII. Stereoselectivities in the Addition of Nucleophiles to Several 4-Uloses

The stereoselectivities in the 1,2-addition of nucleophiles such as methylmagnesium iodide, vinylmagnesium bromide, and 2-lithio-2-methyl-1,3-dithiane to seven kinds of 4-uloses were examined.The configurations of C-vinyl derivatives obtained were determined from the chemical shifts of α-carbons in 13C-NMR spectra.
