Abstract
Enantioselective intramolecular amidation of sulfamate esters catalyzed by chiral manganese(III) Schiff-base complexes under mild conditions (PhI(OAc) 2, Al2O3, C6H6, 5°C) was achieved in moderate to good yields (up to 92%), substrate conversions (up to 99%), with virtually complete cis-selectivity and with ee values up to 79% ee.
