  Synthesis and Dopamine Receptor Modulating Activity of 3-Substituted γ-Lactam Peptidomimetics of l-Prolyl-l-leucyl-glycinamide

  摘要：

  gamma-Lactam. peptidomimetic 2 of Pro-Leu-Gly-NH2 (PLG) was substituted at the 3-position with isobutyl, butyl, and benzyl moieties to give the PLG peptidomimetics 3-5, respectively. These compounds were synthesized to test the hypothesis that attaching a hydrophobic moiety to the lactam ring to mimic the isobutyl side chain of the leucyl residue of PLG would increase the dopamine receptor modulating activity of such peptidomimetics. These peptidomimetics were tested for their ability to enhance the binding of [H-3]-N-propylnorapomorphine to dopamine receptors isolated from bovine striatal membranes. The rank order of effectiveness of the 3-substituent was benzyl > n-butyl > isobutyl > H.

  Double duty: An enantioselective allylic alkylation of aldimine esters has been developed by using a synergistic Cu/Pd catalyst system. This strategy provides access to nonproteinogenic α,α-disubstituted α-amino acids in high yield with excellent enantioselectivity. The more challenging double allylic alkylation of glycinate-derived imine esters was also be realized. LG=leaving group.

• Catalytic α-Allylation of Unprotected Amino Acid Esters

  Catalytic alpha-allylation of unprotected amino acid esters to produce alpha-quaternary alpha-allyl amino acid esters is reported. Catalytic loadings of picolinaldehyde and Ni(II) salts induce preferential reactivity at the enolizable alpha-carbon of amino acid esters over the free nitrogen with electrophilic palladium pi-allyl complexes. Fourteen examples are given. Additionally, the use of chiral ligands to access enantioenriched alpha-quaternary amino acid esters from racemic precursors is demonstrated by the enantioselective synthesis of alpha-allyl phenylalanine methyl ester from racemic phenylalanine methyl ester.
