A model study is presented that paves the way to a new and flexible synthetic approach towards the seco‐ and heteroyohimbine alkaloid class. The key step involves a highly diastereoselective Cope rearrangement of an ( E , E )‐azacyclodeca‐3,7‐diene grafted onto a 3‐ethylindole moiety to furnish a trans ‐3,4‐divinylpiperidine derivative in 83% yield.
