TY - JOUR AB - ~. ~. . ~ ~ .. - A Journal of the ___ ~__~___~-~ Gesellschaft - ~- Deutscher Chemi ker __~ International Edition in English 1996 Pages 353 - 464 ~~ ~~ COVER PICTURE The cover picture shows the catalytic asymmetric aminohydroxylation (AA) of al- kenes in action. Methyl cinnamate can be transformed directly into a derivative of the taxol side chain with the catalyst system K,OsO,(OH), and a phthalazine lig- and; Chloraniine T serves as the nitrenoid source. Either enantiomer can be pro- duced at will by selection of the appropriate ligand. The asymmetric amino- hydroxylation (AA) follows the development of the asymmetric epoxidation (AE) and the asymmetric dihydroxylation (AD)-three reactions whose importance for organic synthesis cannot be overstated. Li. Chang, and Sharpless report more on the new catalytic AA on p. 451 ff. (The cover picture was created by Michael E. Pique. The Scripps Research Institute. La Jolla, CA, USA.)
