| 摘 要： | 1 INTRODUCTION The 10-benzylidene anthrones which are important intermediate for organic syntheses1～3] usually possess thermochromism4] and photo- chromism5], and have been found recently to have evident anti-cancer activity6]. We found that the substituents in the phenyl ring will affect the bioactivity of those compounds. For more deeply investigating the structure-activity relationships (SAR) and understanding interactions between the three dimensional structure of the compound …

Crystal Structure of 10-(2',5'-Dimethoxybenzylidene) Anthrone |
| |
| Abstract: | The anthrone reacts with 2,5-dimethoxybenzaldehyde under base catalyst to afford the title compound (C23H18O3, Mr = 342.37). The crystal belongs to monoclinic, space group P21/c with a = 13.046(4), b = 8.937(2), c = 15.549(4) ? b = 106.52(3) , V = 1738.1(8) 3, Z = 4, Dc = 1.308 g/cm3, m = 0.086 mm-1 and F(000) = 720. The final R = 0.0331 and wR = 0.0850. The results show that the two phenyl rings of the anthrone fragment are not coplanar, but with a dihedral angle of 157.92. The middle ring of the anthrone moiety appears asymmetric boat conformation, while the 2,5-dimethoxyphenyl ring is restricted rotation. Therefore they exist in two optically active forms which are symmetrical glidingly. |
