Isobutylidenation of 1-C-substituted polyols. Attempted extension of the NMR shift rule via the chemical shift difference of their two methyl groups

The isobutylidenation of 1-C-substituted L-threo, D-erythro-glycerols, and D-arabino-tetritol has been studied.The location of the acetal could be adjusted by selecting the conditions for acetalaion as well as the configuration of the polyol.The structure

HETEROCYCLES FROM CARBOHYDRATE PRECURSORS. PART 41. MODE OF FORMATION OF 1,3-DIOXOLANES AND 1,3-DIOXANES FROM 1-C-SUBSTITUTED GLYCEROLS DURING THEIR BENZYLIDENATION

The benzylidenation of 1-C-substituted L-threo- and D-erythro-glycerols has been studied.The correlation of the stereochemical configuration of the glycerolyl part with the formation and location of either the dioxolane or dioxane rings is discussed.The s
