✦ Synopsis
Intermolecular Diels-Alder additions of the readily available dienamides 3 to various dienophiles proceeded in a regio-and stereoselective manner, allowing the preparatTon of complex anilides (z), cyclohexenyl amides (2, 8) and bridged heterocycles (13).

## Abstract In der vorliegenden Mitteilung wird erstmals ein Zugang zu __trans__‐N‐Acyl,N‐alkyl‐1‐amino‐1,3‐butadienen **4**, sowie zu __trans__‐N‐Acyl, N‐aryl‐1‐amino‐1,3‐butadienen **4** beschrieben. Deprotonierung von N‐substituierten 1‐Imino‐2‐butenen **2** führt vermutlich zu den nicht isolier
Recent work in this laboratory has shown N-acylamino-1,3-butadienes (4) to be valuable components for intramolecular Diels-Alder reactions. Thus, heating the dienes 4, R2,R3 = 3-or 4-alkenyl, readily provides complex hydrogenated indolines and quinolines 2) as illustrated by the stereocontrolled
