range of neopentyl boronic esters which, after 1,2-metalate rearrangement and oxidation, gave a range of tertiaryalcohols in high yield and universally high er. Further functional group transformations of the tertiary boronic esters were demonstrated (conversion to quaternary centers, C-tertiary amines) together with application of the methodology to the synthesis of the simplest unbranched hydrocarbon
