【Abstract】 Enantioselectivity of chemical reactions continues to be one of the main concerns of chemists. While many elegant and efficient chiral induction strategies have been developed for a variety of thermal reactions, there are considerably fewer examples of asymmetric induction in photochemical transformations. Short excited state lifetime and low activation energy for reactions in the excited states leave little room for manipulating the diastereomeric transition state when the photochemical reactions occur in solution. The latest progress of asymmetric photochemical reactions revealed that the enantioselectivity in photochemical reactions could be achieved when the reactions take place in chiral environments, which will be reviewed in this article.更多还原
