New preorganized γ-amino acids as foldamer building blocks

Org Lett. 2012 May 18;14(10):2582-5. doi: 10.1021/ol3008815. Epub 2012 May 8.

Abstract

An asymmetric synthesis of two new diastereomeric γ-amino acids is described. Both molecules contain a cyclohexyl ring to limit conformational flexibility about the Cα-Cβ bond; they differ in having cis vs trans stereochemistry on the ring. Residues derived from the cis γ isomer are shown to support helical secondary structures in α/γ-peptide oligomers.
