Optimized diazo scaffold for protein esterification

Org Lett. 2015 May 15;17(10):2358-61. doi: 10.1021/acs.orglett.5b00840. Epub 2015 May 4.

Abstract

The O-alkylation of carboxylic acids with diazo compounds provides a means to esterify carboxylic acids in aqueous solution. A Hammett analysis of the reactivity of diazo compounds derived from phenylglycinamide revealed that the (p-methylphenyl)glycinamide scaffold has an especially high reaction rate and ester/alcohol product ratio and esterifies protein carboxyl groups more efficiently than any known reagent.
