✦ Synopsis

Pathways Involving a Dipolar Intermediate in a Formal 1.3-Sinmatropic Change By Henrik Olsen The cycloaddition reaction between aeodicarbonyl compounds and fulvenes has led to a wide variety of polycyclic nitrogen containing heterocycles Ill. We have discovered that the reaction between N-methyltriaeolinedione (ATAD) and fulvenes & and & provides yet another type of product , namely heptacycles &and a, respectively, formally derived from a Diels-Alder dimerieation of the C6+2l-cycloadducts. Since a 1168+12~1-cycloaddition contravenes the, Woodward-Hoffmann rules /21, the mechanistic details of this reaction were exa-
