Base Hydrolysis of Ester giving racemic product
« on: February 10, 2014, 06:54:39 PM »
Hydrolysis of enantiomerically pure (+) PhCH(Me)COOEt with NaOH in aqueous ethanol gives an extensively racemised acid product. Give a mechanism to explain why.

Attempt: See picture below.

Any help will be greatly appreciated.

The mechanism contains one element of the answer, however it does not explain how enolization happens. There are two possible materials to enolize. Partial should give a clue as to which it is?
