Abstract:
Chiral photochemistry or photochirogenesis is one of the most intriguing, yet challenging topics in current chemistry, as a unique methodology for creating molecular chirality through the electronically excited-state reactions, which is alternative or complementary to the conventional catalytic and enzymatic asymmetric syntheses that already met a great success in the last decades.1-6 Of various strategies developed so far, chiral supramolecular and biomolecular approaches are of particular interest and advantages, where prochiral substrates are confined, pre-organized, pre-oriented, and even accumulated in chiral nanospace before and during the photochemical transformation .
After a brief introduction to the history of photochirogenesis, the recent results of our researches on supramolecular9 and biomolecular10 photochirogenesis will be discussed in successive two lectures (part 1 & 2) by using some selected examples to demonstrate that the photochirogenesis is not only an attractive alternative to the thermal counterpart but also a unique methodology for obtaining chiral compounds through the electronically excited state in the chiral low-entropy environment.
