The X-ray crystal structure of 4-phenyl-5-(2,3,4-trimethoxyphenyl)-isoxole, C18H17NO4, (I) has been determined, revealing an interesting lack of coplanarity for the aromatic rings system. This preferred conformation implies reduction of the conjugation degree, as shown by the C(2)-C(10) and C(3)-C(4) bond-length values. The arrangement of the three methoxy substituents is also examined. 相似文献
