, (2016/10/31)
Methods and reagents for esterification of biological molecules including proteins, polypeptides and peptides. Diazo compounds of formula (I): where R is hydrogen, an alkyl, an alkenyl or an alkynyl, RA represents 1-5 substituents on the indicated phenyl ring and RM is an organic group, which includes a label, a cell penetrating group, a cell targeting group, or a reactive group or latent reactive group for reaction to bond to a label, a cell penetrating group, or a cell targeting group, among other organic groups are useful for esterification of biological molecules. Also provided are diazo compounds which are bifunctional and trifunctional coupling reagents as well as reagents for the synthesis of compounds of formula (I).

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. (Chemical Equation Presented).
