Abstract
The Diels–Alder reaction, with its diverse and extremely rich synthetic potential, is a powerful protocol in synthetic strategies toward natural and unnatural carbo- and heterocycles. This chapter describes multicomponent reaction sequences in which a [4 + 2]-cycloaddition reaction is a key step. In contrast to Section 2.1.7, the focus here is on cycloaddition reactions not involving α, β-unsaturated carbonyl compounds. Examples are described both where the [4 + 2] cycloaddition is the first step in the multicomponent sequence and where the [4 + 2] cycloaddition is a later step in the sequence, with the requisite diene and/or dienophile being formed in the initial steps.
