Syntheses de β- et δ-aryl α-amino esters: reactions d'anions benzyliques chrome tricarbonyle sur des halogeno α-amino esters
Jenhi, A.,Lavergne, J.-P.,Viallefont, Ph.
, p. C14 - C16 (2007/10/02)
Methyl arylacetate-tricarbonylchromium complexes are readily alkylated by halogeno α-amino esters in the presence of NaH or tBuOK to give, after decomplexation, β- and δ-aryl amino esters in good yields.
