9. What would be the major product of the following conversion? 1. NaOMe, MOOH OH O OMe 10. Which product(s) are formed in the tollowing Dieckmann condensation? 1. NaOEt, EIOH EtOOC COOE 2.Ho d. both a) and b) e. a), b), and c) COOEt COOEt b 11. Consider the synthesis below. What is compound Q? COOH COOEt 1. KOBu 1. NaOH, H2O, heat 2. Q 3. heat (-CO2) d. e. Eto C. 12. Why is CH,ONa not used in the Claisen condensation of ethyl acetate? a, b. c. CH30-is a weaker base than CHCH,0-which would be the preferred choice CH,0-Na, is more difficult to prepare than CHCHONa. CH,0 would abstract a proton from the ethyl group of the ester. Use of CH,O Na' would result in transesterification. CH30-Na, can be used as well as CHCH2ONa. e.
