Dpering (1) was the first to demonstrate the ability of suitably disposed vinylpyridincs to serve as electrophilic olefins in Michael addition reactions. Subsequent studies (2,3) have elaborated the acope of this reaction.

## Abstract Heating of oxepines and oxacenes of type (I) and (IV) as well as cyclobutanecarboxaldehydes like (VII) with Staudinger reagents is found to provide an efficient approach to medium ring nitrogen heterocycles.
The reaction of heterocyclic enamioes with ethyl propiolate and diethyl acetylenedics&oxylate has been systematically studied. In contrast to their hetemcyclic ketene aminal analogues, heterocyclic enamines reacted with electrophilic e w'a the Michael addition pathway rather thao the aza-ene reactio
