| Research Abstract |
In this project, the metal complex-catalyzed asymmetric reactions were combined with photo-irradiation for supplying novel chiral compounds. For an example, the Friedel-Crafts/Henry reaction of indoles, nitroalkenes, and aldehydes, gave the three components coupling compounds having new contiguous stereogenic centers by the combination use of photo-isomerization of trans-nitroalkenes to the cis-nitoroalkenes. The method was also applicable to the [3+2]-cycloaddition of nitroalkenes with iminoesters. Moreover, the photo-irradiation was effective for controlling the activities of metal-proton cooperative catalyst.
