    • This chapter lists >500 examples of the Stetter reaction involving 93 different aldehydes. In terms of the Michael acceptor, the vast majority are unsubstituted at the β position, or are quite activated (maleates, fumarates, chalcones, etc.). Five examples contain simple alkyl substitution at the β position of the Michael acceptor [cyclopentenone (30% yield), pentenone (34% yield), and ethylidineacetoacetate (3 examples, 32-49% yields)]
