Popis:	Photolysis of a tethered cyclooctene (E)-4, in which the sensitizer benzoate is connected to the olefin moiety through a chiral 2,4-pentanediol tether, afforded the Z/E ratios up to 0.8 and the diastereomeric excess of 33% at −65 °C, while the terephthalate analogue (E)-5 gave higher de of 44% at the same temperature.
