Cyclofunctionalization of Hydroxyolefins Induced by Arenetellurinyl Acetate

Treatment of arenetellurinic anhydride (1) with acetic acid or anhydride readily formed arenetellurinyl acetate (2).It underwent not only oxytellurinylation of an olefin but also intramolecular cyclofunctionalization of various hydroxyolefins to cyclic ethers.The latter reaction was effectively accelerated by addition of boron trifluoride etherate or tin(IV) chloride and highly regio- and stereoselective.The tellurium functional group introduced in the cyclic ethers could be manipulated into other versatile groups by telluroxide elimination, halogenolysis, and reductive detelluration.

NEW SYNTHETIC REACTIONS USING ARENETELLURINIC ANHYDRIDES

New synthetic reactions utilizing arenetellurinic acid anhydrides are described.The anhydrides proved to be very useful reagents for the transformation of various functional groups.Furthermore they induced various intramolecular cyclofunctionalizations to yield many oxygen and nitrogen heterocycles.

CYCLOFUNCTIONALIZATION OF HYDROXYOLEFINS INDUCED BY ARENETELLURINIC ANHYDRIDE

Arenetellurinic anhydride reacts with hydroxyolefins in acetic acid at reflux to give cyclic ethers bearing a phenyltelluro group.A mechanism via intramolecular oxytellurinylation with arenetellurinyl acetate is proposed.

CYCLOFUNCTIONALIZATION OF UNSATURATED ALCOHOLS WITH ARYL TELLURIUM TRIHALIDES

The reaction of unsaturated alcohols with aryltellurium trihalides leads to cyclic ethers bearing an aryldihalotelluro group in the β position, in high yields.Reduction of the tellurium-halogen bond with thiourea dioxide gives the corresponding tellurides
