Post-lab questions (1) In a Michael reaction, an α carbon attacks the β carbon of an α,β-unsaturated carbonyl com pound to afford a 1,5-dicarbonyl compound. Ethyl acetoacetate has two a carbons: why does the a carbon sandwiched between the two carbonyls conduct the attack? Ph Ph 0 Ph Michael OCH2CH3 5 OCH2CH3 OCH2CH 0 This forms... ...not this: Why?
