    A route towards I-oxygenated eudesmanolides, via a (2+2) photocycloaddition reaction for constructing the decalin framework is described. The following natural substances have been synthesized. (=)-dihydroreynosin (1), (±)-1- oxo-dihydronmagnolialide (2), (±)-maritimin (3), (±)-dihydromagnolialide (4), (±)-magnolialide (5), (±)-dihydrosantamarine (6). Also a synthesis of (±)--santonin (7) is presented
