An epoxide formed at the more substituted double bond.

(A) $MCPBA$ is a peroxyacid that reacts with alkenes to form epoxides (oxiranes). In a molecule with multiple double bonds,the reaction is regioselective. The rate of epoxidation increases with the electron density of the double bond. Therefore,the more substituted (more nucleophilic) alkene reacts faster with $MCPBA$ to form the epoxide.
