  • An improved method for acylation with acid chlorides utilizes the Rathke MgCl2-triethylamine reagent in acetonitrile or ethyl acetate to give ?-keto esters in very high yields: Synthesis, 290 (1993):
  • Compare Diethyl malonate, A15468 and Dimethyl malonate, A11007, for other applications of this technique. See also Ethyl hydrogen malonate, A12627.
  • Alternatively, ?-keto esters can be obtained in high yield by reaction with TMS chloride to generate ethyl trimethylsilyl malonate, followed by in situ reaction with acyl imidazoles or acyl chlorides in the presence of DBU: Tetrahedron Lett., 35, 9323 (1994).
