Abstract

Numerous examples for Diels-Alder reactions with singlet oxygen (lo2) as the dienophile have been published. In most cases, the reactive cis-1, 3-butadiene grouping is incorporated in nonaromatic or in carbo-and heteroaromatic ring systems such as cyclopentadienes, anthracenes, and furans, respectively.'Acyclic 1, 3-butadienes have been studied to a much lesser extent. Depending upon substitution, acyclic 1, 3-butadienes may ...
