## Abstract The reactivity and selectivity of the the captodative olefins 1‐acylvinyl benzoates **1a**–**1f** and **3a** as heterodienes in hetero__‐Diels__–__Alder__ reactions in the presence of electron‐rich dienophiles is described. Heterodienes **1** undergo regioselective cycloaddition with th

✦ Synopsis
Part 3 of 'Thermal Reactions of Donor-Acceptor Systems'. Part 2: [I].
Taken in part from the diploma thesis (KWTH 1986) and from the planned Ph. D. thesis. The interactions of both pairs of frontier orbitals have to be considered in the so-called neutral (type 11) LXels-Alder reaction. Examples, however, are not frequent [2].
No formation of products from 8 and 2 has been observed under normal pressure at 80".
The crude product contains two further 1 : 1 adducts (0.9 and 1.4%, resp.) according to GC/MS analyses
