This Letter has been retracted by the authors upon request of the Editorial Board
for reasons of significant content overlap with a parallel submission to another journal.1
The Editorial Board recognizes that, had the submission to Chem. Commun. (submitted five weeks prior to this Synlett manuscript), been referenced and its contents disclosed, the striking similarities
between the chiral (Chem. Commun.) and racemic (Synlett) syntheses would have been noted and the Synlett Letter would not have been accepted for publication.
