Popis: | Palladium-catalyzed intramolecular aryl etherification reaction using bulky binaphthylphosphane ligand is shown to be a convenient method for the synthesis of seven-membered heterocy- cles. Application of this methodology to a naturally occurring pro- teinogenic L-amino acid has led to the synthesis of optically active benzoxazepine ring systems of versatile biological importance. |
