Corrigendum: Chiral Neutral Zirconium Amidate Complexes for the Asymmetric Hydroamination of Alkenes

Abstract

The authors would like to thank Prof. Kai Hultzsch of Rutgers University for alerting them to their erroneous illustration of the tetrasubstituted stereogenic center in the Mosher amide derivatives as S in the Supporting Information. The authors have verified, with the assistance of Prof. Hultzsch, that the method and NMR data presented in the Supporting Information gives the correct configuration of 2-methyl-4,4-diphenylpyrrolidine as indicated.1 While the illustrated and assigned configuration of the pyrrolidine products in both the manuscript and Supporting Information are correct,1 because of the Cahn–Ingold–Prelog priorities in assigning configuration there is a change from S to R upon amide synthesis. Thus, the use of (S)-Mosher acid chloride gives the (R)-Mosher amide products. To ensure that this error is not propagated in the literature, a revised version of the Supporting Information has been filed with all of the corrected illustrations included on the spectra. The sentence at the bottom of the first column on page 356 should be corrected to read “Reported ee values were determined by integration of 1H and/or 19F NMR spectra of the (S)-Mosher acid chloride derivatives of at least two independent experiments.” The authors regret any confusion that may have arisen from their erroneous illustration. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents are peer-reviewed, but not copy-edited or typeset. They are made available as submitted by the authors. Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.
