This chemist is the first namesake of a reaction between acetophenone and benzaldehyde derivatives thatyields chalcones. That reaction is an aldol condensation of an aromatic aldehyde with an aliphatic ketone inthe presence of a base or an acid to form an alpha,beta-unsaturated ketone. The other namesake of thatcondensation is Schmidt. The rearrangement named for this chemist takes allyl vinyl ethers to yieldgamma,delta-unsaturated carbonyl compounds. That [3,3]-sigmatropic rearrangement is very closelyrelated to one named for Cope, and has over twenty named variations. Yet another reaction named for himhas an intramolecular form named for Dieckmann. For 10 points, name this German chemist whosenamesake condensation transforms esters with alpha-hydrogens to beta-ketoesters when promoted by abase, like sodium ethoxide.
