IntroductionJiaxi Xu completed his Ph. D. in organic chemistry at Peking University in 1992. After a post-doctoral research at Beijing Medical University, he was appointed as an associate and full professor in Peking University during 1994-2007. He also worked as visiting scholar in Hong Kong and United States. Currently, he is a professor in College of Chemistry at Beijing University of Chemical Technology. EducationWork ExperienceSocial PositionSocial ActivitiesResearchHis research interests include synthetic methodology and related mechanism, stereochemistry and asymmetric catalysis. His research group developed synthetic methods of various substituted taurines, convergent synthesis of phosphonopeptides. He has been especially interested in the stereochemistry and formation mechanism in the synthesis of b-lactams and b-sultams from imines and ketenes or alkanesulfonyl chlorides via the Staudinger cycloaddition and sulfa-Staudinger cycloaddition. He revealed the origin of the diastereoselectivity in the Staudinger cycloaddition. He also elucidated the annuloselectivities (annulation selectivities between [2+2] annulation and [2+2+2] annulation) in the reactions of imines with ketenes or sulfenes or their equivalents and stereochemistry of [2+2+2] annulation. He developed a series of synthetic methods for substituted taurines, alfa-aminoalkylphosphonic acid derivatives, and phosphonopeptides.
