Abstract
The intramolecular hetero-Diels-Alder reaction of vinylallenes and imines has been
carried out. Depending on the substituents on the allene and the length of the tether
linking diene and heterodienophile, the reaction proceeds thermally or with Lewis
acid activation. The transformation of one of the adducts into a 9-substituted octahydroacridine
is reported.
Key words
vinyl allenes - intramolecular reaction - hetero-Diels-Alder reaction - imines - cycloaddition

The term semicyclic refers to a dienic or vinylallenic system in which only one of
the double bonds is a part of a cycle.
