Acyclic stereoselection using relative 1,2-asymmetric induction. A convenient method for the stereoselective construction of α,γ-dimethyl-α,β-dihydroxy compounds, useful intermediates for synthesis of erythronolides
Abstract
Highly Stereoselective addition of dithiane anions with 2-methyl-3-trimethylsilylbut-3-enal combined with the stereoselective addition of Grignard reagents to chiral α-alkoxyketones affords a practical and efficient method for the construction of the title compounds.
