摘要
From simple to complex: Starting from easily accessible isoquinolones 1 (X=Br, OH), complex cyclobutane photoproducts such as compound 2 can be obtained with high enantioselectivity (88-96% ee) through the use of a chiral template. Compound 3, which was isolated in 53% ee starting from a racemic substrate, is the product of a unique, unprecedented kinetic resolution process. © 2011 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
