## Abstract Irradiation of a pentane solution of (__E__)‐dehydro‐β‐ionone‐epoxide (**1**) with light from a medium pressure mercury lamp using acetone as filter led to formation of the __isomers__ **2**, **3, 4** and **5** by novel photochemical processes.
In, n \*-Excitation of the y, 6-epoxy-enone (E)-3 leads exclusively to the conformers (%)-3A + B. On 'n, n\*-excitation of (E)-3, in addition to (%)-3A + B, products &9 arising from a carbene intermediate e are formed. However. products of an isomerization via C(y),O-bond cleavage of the oxirane wer
