## Abstract In der vorliegenden Mitteilung wird erstmals die Stereochemie intramolekularer En‐Reaktionen in Beziehung zur Geometrie der En‐Komponente systematisch beschrieben sowie ein neuer, präparativ ergiebiger Weg zu substituierten Pyrrolidinen aufgezeigt. Die N‐(__cis__‐Crotyl)‐N‐allylamide **
## Abstract The pyrrolidines **2** and **10** were obtained by thermal ene‐reactions at +70° and +180° from the (__Z__)‐4‐aza‐1, 6‐diene **1** and from the (__E__)‐4‐aza‐1, 6‐diene **9** in the ratios of 75:25 and 50:50, respectively. On the other hand, these cyclizations proceeded readily in the p
## Abstract The racemic sesquiterpene isocomene (**1**) has been synthesized starting from 1,7‐octadien‐3‐one (**2**) in a stereoselective manner __(Scheme 2)__. In the key step **4** → **5** the C(7), C(8)‐bond was formed by an intramolecular thermal ene reaction. Further elaboration of **5** invo
