## Abstract The diastereoselective radical tandem additionโcyclization reaction of __N__,__N__โdimethylaniline (**2**) with menthyloxyfuranone **1** was initiated by photochemically induced electron transfer using inorganic semiconductors (TiO~2~, ZnS, SiC and SnO~2~) as sensitizers. The rearomatiz
Tertiary amines derived from pyrrolidines can be added veD' efficiently (isolated yields up to 94%) to (SR)-5-mentyloxy-2[5H]-furanone. The addition, which follows a radical chain mechanism initiated by a photoinitiated electron transfer (PET) from the tertiary amine to the excited aromatic ketone,
