当紫外光照射具有(R)-N-苯乙酰胺取代基的二硫代六氟环戊烯的氢键受限晶态时，光化学环化反应非对映选择性地进行，生成有色的闭环异构体，De为97%。
Upon UV irradiation of the hydrogen-bond confined crystal state of a dithienylhexafluorocyclopentene with (R)-N-phenylethylamide substituents, the photochemical cyclization reaction proceeds diastereoselectively to form the coloured, closed-ring isomer with 97% de.
