Abstract

The total synthesis of the phytoalexin (±)-lubiminol 1 has been accomplished. The synthesis relies on a conjugate addition-cyclization reaction to prepare a photosubstrate for a stereoselective intramolecular photoaddition reaction. The photoadduct is transformed into the required spiro [5.4] decane through a radical fragmentation-rearrangement reaction.
