1. Alkylation by Asymmetric Phase- Transfer Catalysis 张文全

2. Keiji Maruoka, Professor Keiji Maruoka was born in 1953 in Mie, Japan. He graduated from Kyoto University (1976) and received his Ph.D. (1980) from University of Hawaii(Thesis Director: Prof. H. Yamamoto). He became an assistant professor of Nagoya University (1980) and was promoted to a lecturer (1985) and an associate professor (1990) there. He moved to Hokkaido University as a full professor (1995-2001), and he currently is a professor of chemistry in Kyoto University since 2000. (2007/2008). He is a board member of Chem. Commun. and is a member of the international advisory editorial board of Org. Biomol. Chem. And Chem. Asian J. His current research interests include bidentate Lewis acids in organic synthesis and practical asymmetric synthesis with chiral C2-symmetric phase-transfer catalysts and chiral bifunctional organocatalysts..

8. almost all of the elaborated chiral phase-transfer catalysts reported so far have been restricted to cinchona alkaloid derivatives, which unfortunately constitutes a major difficulty in rationally designing and fine-tuning catalysts to attain sufficient reactivity and selectivity for various chemical transformations under phase-transfer catalyzed conditions Design new PTC catalyst which contain C2-Symmetry J.
