  Toward the Development of a General Chiral Auxiliary. 9. Highly Diastereoselective Alkylations and Acylations to Form Tertiary and Quaternary Centers

  摘要：

  [GRAPHICS]Enolates of a new camphor-derived lactam auxiliary are shown to monoalkylate with very high diastereoselectivity. A second alkylation occurs with reactive alkylating agents to afford quaternary centers also with high diastereoselectivity, In accord with a proposed model for diastereoselection, lithium and sodium enolates provide products with an opposite sense of asymmetric induction.

  (+)-2-Isopropyl-2-methylglutaric acid has been prepared from (+)-2-isopropyl-2-methylsuccinic acid. The absolute configuration of these acids has been defined as S by an X-ray crystallographic examination of (+)-rubidium 1-methyl 2-isopropyl-2-methylsuccinate.
