Abstract
Fragmentation of unsaturated photoadduct derivatives 5 and 8 with (n-B u)(3)SnH, (C6H5)(3)SnH or SmI2 generally gives mixtures of regioisomer s. SmI2, is the reagent of choice for these transformations because th e yields art high (> 90%) and with esters 8a/b only one isomer, 11a/b, is obtained.
