Chiral photogeneration using perfluorocyclopentene-derived photochromes.
A new type of perfluorocyclopentenes which contain an optically active group at the 2-position of the thiophene ring were synthesized. Irradiation with UV light afforded the cyclized diastereoisomers in ratios dependent on solvent polarity and temperature.
