A Convenient Strategy for the Synthesis of 4,5-Bis(o-haloaryl)isoxazoles

A series of new 1,2-bis(o-haloaryl)ethanones is efficiently prepared and applied to the synthesis of 4,5-bis(o-haloaryl)isoxazoles. Isolation of intermediate hydroxyisoxazolines, which are structurally examined, provides a definitive proof for a heterocyclization mechanism based on an amine exchange process. The isolation and X-ray crystallographic studies of significant side products such as benzamides and triarylpropionitriles are also described.

ISOLATION OF STILBENE DERIVATIVES IN THE BROMINATION OF 1,2-DIARYL-ETHYLAMIDES

The bromination reaction of the 1,2-diaryl-ethylamides (1a-d) afforded the expected bromoamides, together with two stilbene derivatives as by-products: the (E)-1-(2-bromo-4,5-dimethoxyphenyl)-2-(3,4-dimethoxyphenyl)-ethylene (3) and the (E)-1,2-bis(2-brom
