Intramolecular site selectivity in cation radical Diels-Alder cycloadditions of difunctional and trifunctional dienophiles

Bauld, Nathan L.,Yang, Jingkui

, p. 518 - 522 (2007/10/03)

The cation radical Diels-Alder reactions of several difunctional and trifunctional dienophiles with 1,3-cyclopentadiene, catalyzed by tris(4-bromophenyl)aminium hexachloroantimonate, were determined. When both of the reactive sites are of the 4-methoxysty
