Oxidative Cyclization of Sulfamates onto Pendant Alkenes
Anand H. Shinde, Shyam Sathyamoorthi
Abstract
This communication discloses the first examples of aza-Wacker cyclizations of sulfamate esters. Within the realm of related cyclization reactions, this protocol is differential in that it forms six-membered rings in good yield and uses catalytic amounts of palladium(0) rather than palladium(II) salts. These reactions scale well, and their products are demonstrated to be valuable synthetic intermediates.
