carboyxlic acids to cyclic esters
    #3365467 - 11/15/04 07:53 PM (13 years, 7 months ago)

anyone know how to take a carboyxlic acid and make it a cyclic ester? I am aware of the method used for making a hydroxy carboxylic acid to a cyclic ester, only I don't know how to make a carboyxlic acid into a hydroxy carboyxlic acid.

would love your help!

Carboxylic acids with an alpha-H can react with dihalogens in the presence of a lewis acid to make a halocarboxylic acid, which can then of course be converted to a hydroxy-CA. Its an HVZ reaction but you knew that, right?

Wouldn't intramolecular esterification occur in presence of acid?

Catalysis what is a HVZ reaction?

> what is a HVZ reaction

Hell-Vollhardt-Zelinsky Reaction used for alpha-bromination of carboxylic acids (if I remember my organic chemistry correctly, it has been many years).
