Abstract

Standard Boc, Alloc, and Cbz derivatives of N-2,4-dimethyl-6-iodophenyl-N- allyl anilines are axially chiral and can be readily resolved into atropisomers whose racemization barriers exceed 30 kcal/mol. The resolved axially chiral carbamates undergo radical and anionic cyclizations with high levels of chirality transfer from the N-Ar axis to the new stereocenter in the substituted dihydroindole products. The carbamate groups of the products are readily removed. © 2009 American Chemical Society.
