A variety of cyclopropanone acetal derivatives were found to undergo facile Fe(III) mediated oxidative radical cyclisation to the corresponding trisubstituted cyclopentane esters in good yield and with diastereoselectivities as high as 23:1.

Treatment of the cyclopropanone acetals 7 or 11 with three different FeIII species gives the lactone 9 and the ester 13 respectively via an oxidative cyclopropane cleavage followed by a 5-exo radical cyclisation–abstraction sequence.
