Mosher's acid, via its acid chloride derivative, reacts readily with alcohols and amines to give esters and amides, respectively. The lack of an alpha-proton on the acid prevents loss of stereochemical fidelity under the reaction conditions. Thus, using an enantiomerically pure Mosher's acid allows for determination of the configuration of simple chiral amines and alcohols. For example, the (R)- and (S)-enantiomers of 1-phenylethanol react with (S)-Mosher acid chlorid… WebMosher Jeff’s Post Mosher Jeff Artist / Blacksmith Hand wrought ornamental iron work , from lighting to fireplace sets , railings, gates 1y Report this post ...
