Abstract
Palladium-catalyzed intramolecular aryl etherification reaction
using bulky binaphthylphosphane ligand is shown to be a convenient
method for the synthesis of seven-membered heterocycles. Application
of this methodology to a naturally occurring proteinogenic l -amino acid has led to the synthesis of
optically active benzoxazepine ring systems of versatile biological
importance.
Key words
amino acids - palladium - ligand - etherification - chiral benzoxazepines

g cm-³ , F( 000) = 200.
Diffraction data were measured with Mo-Kα (λ = 0.71073 Å)
radiation at 296 K using a Bruker Kappa Apex 2 CCD system. A total
of 2595 unique reflections were measured (θmax = 28.18˚).
Data analyses were carried out with the Fast Fourier Transform program.
The structures were solved by direct methods using the SHELXS-97²²
program. Refinements were carried out
with a full matrix least squares method against F 2
using SHELXL-97.²³
Non-hydrogen
atoms were refined with anisotropic thermal parameters. The final R value was R 1 = 0.0479
and wR 2 = 0.1255
with I > 2σ (I ). Crystallographic data have been deposited
at the Cambridge Crystallographic Data Centre with reference numbers
CCDC 776221. These data can be obtained free of charge at www.ccdc.cam.ac.uk/conts/retrieving.html
