Which, if any, of the following compounds can be prepared by a malonic ester
synthesis? Show the alkyl halide you would use in each case.
(a) Ethyl pentanoate

Aspirin is an anti-inflammatory agent because it inhibits the conversion of arachidonic acid to prostaglandins by the transfer of its acetyl group (CH3CO−) to an OH group at the active site of an enzyme. This reaction, called transesterification, results in the conversion of one ester to another by a nucleophilic acyl substitution reaction. Draw a stepwise mechanism for the given transesterification.
Show how you would synthesize each compound, starting with an ester containing nomore than eight carbon atoms. Any other necessary reagents may be used.(a) Ph3C¬OH (b) (PhCH2)2CHOH
