In a variant of a reaction named for this chemist, an allylic ester acts as an enolate anion in the presence of a strong base to form a carboxylic acid; that reaction is co-named for this chemist and Ireland. (15[2])This (15[1])chemist (15[1])is the alphabetically (15[1])former namesake of (15[1])a crossed aldol process in which an alpha-hydrogen attacks an aromatic compound with no alpha-hydrogen. This chemist reacted ethyl acetate and benzaldehyde to generate the ester of ethanol and (*) cinnamic acid. When a reaction named for this chemist is run on succinic (“SUCK-sin-ick”) acid, it can be performed using less strong bases in a modification named for Stobbe. (10[1])An allyl vinyl ether is heated to form a gamma-delta unsaturated carbonyl in a reaction named for this chemist with an intramolecular equivalent named for Dieckmann. (10[1])For 10 points, name this German chemist who names a [3,3]-sigmatropic rearrangement (10[1])as well as a reaction in which two esters form a beta-keto ester. ■END■
