Orthogonal N,N-deprotection strategies of beta-amino esters
β-Amino esters derived from the stereoselective conjugate addition of homochiral lithium N-benzyl-N-α-methyl-4-methoxybenzylamide to α,β-unsaturated esters may be orthogonally mono-N-deprotected under either oxidative or acid-promoted reaction conditions. Further oxidative deprotection affordsβ-amin...

| Riassunto: | β-Amino esters derived from the stereoselective conjugate addition of homochiral lithium N-benzyl-N-α-methyl-4-methoxybenzylamide to α,β-unsaturated esters may be orthogonally mono-N-deprotected under either oxidative or acid-promoted reaction conditions. Further oxidative deprotection affordsβ-amino acids or β-lactams. |
