BackThe Knoevenagel condensation is a special case of the aldol condensation in which an active methylene compound reacts with an aldehyde or ketone, in the presence of a secondary amine as a basic catalyst, to produce a new C=C. Show the starting materials that made each of these by a Knoevenagel condensation.
(a)
Show how you would use an aldol, Claisen, or another type of condensation to make each compound.
(a)
Propose mechanisms for the reactions shown in Problems 22-63 part (b).
Show how you would use an aldol, Claisen, or another type of condensation to make each compound.
(f)
Propose a mechanism for the crossed Claisen condensation between ethyl acetate and ethyl benzoate.
