Reaction Steps

Cyclopentene reacted with carbon monoxide (CO) and hydrogen (H2) in the presence of a Wilkinson's catalyst to provide cyclopentanecarboxaldehyde, which then reacted with methylmagnesium chloride (MeMgCl) to provide 1-cyclopentylethanol, which further reacted with crotonic acid in the presence of p-toluenesulfonic acid (pTSA) to afford product but-2-enoic acid 1-cyclopentyl-ethyl ester.
