Bromophenyl magnesium reagents generated via a Knochel type magnesium halogen exchange of aryl iodides undergo regioselective ring opening of cyclic primary and secondary N-Boc sulfamidates in good to excellent yields. With secondary sulfamidates the reaction proceeds with clean inversion of the stereochemistry. This protocol complements the ring opening of aziridines with bromophenyl metal reagents and extends its scope to secondary substrates. (C) 2011 Elsevier Ltd. All rights reserved.
