Synthesis of 4-substituted-3-aminopiperidin-2-ones: Application to the synthesis of a conformationally constrained tetrapeptide N-acetyl-Ser-Asp-Lys- Pro

A new and practical synthetic strategy is developed for the synthesis of six-membered lactam-bridged dipeptides, 4-substituted-3-aminopiperidin-2-ones, featuring two key steps: (a) a diastereoselective addition of cuprate to (E)-α,β-unsaturated ester (3)

A novel approach for the asymmetric synthesis of (3S,4R)-3-amino-4-alkyl-2-piperidinones: Conformationally constrained dipeptides

A straightforward method is developed for the synthesis of enantiopure (3S,4R)-3-amino-4-alkyl-2-piperidinone derivatives, six-membered lactam-bridged dipeptides, via highly diastereofacial selective 1,4-addition of organocuprate to the chiral oxazolidine
