spacer between the central methano-carbon and benzene ring, is reported. In an approach towards asymmetric tetrasubstituted methane with high enantioselectivity, chiral tertiary α-hydroxyaldehyde has been synthesized through a Sharpless dihydroxylation on a disubstituted olefin, followed by the chemoselective oxidation of the primary alcohol.
