A de novo approach for the synthesis of biologically important C-galactosides has been achieved via use of an acyclic galactose-derived β-keto ester. The β-keto ester enolate serves as a C-nucleophile and reacts with primary alkyl halides and Michael acceptors to generate alkylation products that can be converted into β-C-galactosides and C-disaccharide mimics with high stereoselectivity.
