MgCl2-mediated nucleophilic addition/deacetylation sequence in the presence of a base in an alcoholic solvent. Salient merits of this chemistry include step-economy, ease of work-up, mild conditions, broad substrate scope, functional group tolerance and scalability. The high efficiency and practicability enabled rapid access to diverse precursors of malonamides for use in pharmaceuticals.
