Cumulated Ylides, XVI. A Method for the Exchange of the OH Group in Free Carboxylic Acids by the Ylide Function

Carboxylic acids 5 react with triphenylphosphorane (4) via the intermediate 6 with formation of the phosphoranes 7, which rearrange by heating in an intramolecular acyl migration to ylides 10.By heating of 10 in the presence of an alcohol 13 the acyl ylides 11 and urethanes 14 are formed.The reaction sequence allows the replacement of the OH group in carboxylic acids by the ylide function.
