  Stereoselective synthesis of .beta.-lactams by oxidative coupling of dianions of acyclic tertiary amides

  摘要：

  Tertiary amides RCH2CON(R')CH2Z, where Z is an electron-withdrawing group, were converted into dianions by treatment with 2 equiv of n-butyllithium or tert-butyllithium, and the dianions were oxidized with N-iodosuccinimide (NIS) or a Cu(II) carboxylate to form beta-lactams stereoselectively. The stereochemistry of beta-lactam formation depends on the oxidant; NIS is cis-selective, whereas Cu(II) is nonselective or slightly trans-selective. A high degree of asymmetric induction in the formation of beta-lactams was achieved by using (R)-1-phenylethylamine as a chiral auxiliary. This asymmetric ring closure was applied to the preparation of cis-beta-lactam 31, an intermediate for the synthesis of the monobactam antibiotic carumonam.
