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 in.....
