  additions to ethylenic and acetylenic acceptors under appropriate solid-liquid phase transfer catalysis conditions. Further transformations of the α-disubstituted ketimines lead to α-alkylated aspartic and glutamic acid derivatives 10, 15, 19 and 26, to bicyclic amino acids or derivatives featuring pyrazolone and isoxazolone moieties 30 and 33, and to α-substituted (E)-3,4-dehydroglutamic acids.

  Ethyl N-diphenylmethyleneglycinate reacts with one equivalent of alkylating agents in the presence of powdered potassium carbonate to afford, after hydrolysis, monoalkylated glycine esters. A similar process using two equivalents of alkylating agents in the presence of powdered potassium hydroxide and a phase transfer catalysts gives, after hydrolysis, dialkylated glycine esters.

  Abstract A general and efficient synthetic route to α-amino acids by alkylation of the sodium salt of Schiff base ester 1 has been described previously. The α-substituted ethyl glycinates 4a–g are prepared in excellent yield by a two-step sequence involving regioselective alkylation of the anionic glycine synthon 2 with various alkyl halides, followed by purification of the alkylated Schiff base on
