✦ Synopsis

Irradiating cyclohexenones containing an olefinic side chain under electron transferconditions (PET) leads to new spirocyclic products 3, as well as [2+2]-cycloaddition products 2. A new reductive cyclobutane ring opening allows photochemical conversion of cyclobutanes 2 to spirocyclic compounds 3.

## Abstract The diastereoselective radical tandem addition‐cyclization reaction of __N__,__N__‐dimethylaniline (**2**) with menthyloxyfuranone **1** was initiated by photochemically induced electron transfer using inorganic semiconductors (TiO~2~, ZnS, SiC and SnO~2~) as sensitizers.

Cyclopropyl radicals normally undergo complete thermodynamic equilibration of configuration before they react, e.g., with bromine in the Hunsdiecker reaction'. Incomplete equilibration is normally due to steric or cage effectsa, and to surface effects when cyclopropyl halides are reduced with metals
