Steric limits to ester alkylation; synthesis of highly hindered esters via hexamethylphosphoramide-favoured enolization

αα-disubstituted from α-monosubstituted esters takes place in high yields and appears to be only slightly influenced by the nature of the alkylating agent (Mel, Etl, or Pril). In contrast, the formation of ααα-trisubstituted for αα-disubstituted esters appears to be sensitive to the steric nature of the ester to be alkylated. Thus in the synthesis of tri-from mono-substituted esters the order of introduction of
Organocatalytic Enantioselective 1,3-Dipolar Cycloadditions between Seyferth–Gilbert Reagent and Isatylidene Malononitriles: Synthesis of Chiral Spiro-phosphonylpyrazoline-oxindoles

A new method has been developed for the catalytic enantioselective 1,3-dipolar cycloaddition of the Seyferth–Gilbert reagent (SGR) to isatylidene malononitriles using a cinchonaalkaloidderivative as a catalyst. This method allowed for the synthesis of a series of chiral spiro-phosphonylpyrazoline-oxindoles in good yields with excellent enantioselectivities. The synthetic utility of this method was
