  A Study on the Asymmetric Synthesis of β-Lactams through Double Stereodifferentiating Cycloaddition Reactions

  摘要：

  The cycloaddition reaction of chiral aminoketenes, generated from their corresponding acid chlorides and triethylamine, with chiral imines is evaluated as the most direct approach for the construction of cis-beta-lactams with the absolute stereochemistry at the C-3 and C-4 positions being controlled by the ketene partner, independently of the absolute stereochemistry of the imine component.

  The design and synthesis of 9, an analogue of deoxybouvardin (2), is detailed. The substitution of the beta-lactam in 9 for the 14-membered N-methylcycloisodityrosine subunit of 2 serves to mimic the unusual beta-turn possessing a central cis amide bond found in the natural product and restricts and restricts the accessible conformations of the remaining tetrapeptide (D-Ala-Ala-N(Me)-Tyr(OMe)-Ala) to those including that found in the solution and X-ray conformation of the natural product.
