Question

Quizplus · Accepted Answer

In a poorly planned crossed aldol reaction, four different aldol regioisomers can be produced due to the mixing of two different carbonyl compounds and two different enolates. Each carbonyl and its corresponding enolate may react with either the other carbonyl or enolate, yielding four possible regioisomers.
