A proline-based phosphine template for Staudinger ligation

Org Lett. 2012 Sep 7;14(17):4694-7. doi: 10.1021/ol3022484. Epub 2012 Aug 27.

Abstract

A proline-based phosphine template enabling a rapid Staudinger ligation of azide-containing substrates under mild conditions is reported. This reaction has a second-order rate constant of 1.12 M(-1) s(-1). It is expected that the proline-based Staudinger ligation strategy will be a useful method for bioconjugation and proline based peptide coupling.
