4b. Provide a reason why anionic-enolate-based aldol condensation chemistry might lead to top regioisomer, whereas secondary amine-mediated aldol condensation chemistry would lead to the bottom regioisomer. You do not need to show full mechanism, but should show the important structures. NaOH Me Me || Me Me Me Me Me 1OAc Me Me
