摘要：The present invention relates to novel intramolecular amidation processes forsubstrates such as sulfamate esters using chiral and non-chiral metalloporphyrincomplexes, which can maximize catalytic activity and enhance efficiency, stereoselectivityand speed of amidation of these substrates. The intramolecular amidation of sulfamateester exhibits excellent cis-selectivity, affording cyclic sulfamidates with high ee valuescatalyzed by chiral metalloporphyrin.
