Intramolecular amidation of sulfamate esters catalyzed by metalloporphyrins

Summary: The present invention relates to novel intramolecular amidation processes for substrates such as sulfamate esters using chiral and non-chiral metalloporphyrin complexes, which can maximize catalytic activity and enhance efficiency, stereoselectivity and speed of amidation of these substrates. The intramolecular amidation of sulfamate ester exhibits excellent cis-selectivity, affording cyclic sulfamidates with high ee values catalyzed by chiral metalloporphyrin.
