1,2-二[3-(6-甲基-8-叔丁基-3,4-二氢-1,3-苯并噁嗪)基]乙烷与新型双氮桥联四酚化合物的合成

Synthesis of 1,2-Bis(8-t-butyl-6-methyl-2H-benzo-[e][1,3]oxazin-3(4H)-yl] ethane and Novel Bridged Tetra(phenol) Compound

2-叔丁基-4-甲基苯酚、甲醛和乙二胺在甲醇中回流反应2 h,高产率地合成了1,2-二[3-(6-甲基-8-叔丁基-3,4-二氢-1,3-苯并噁嗪)基]乙烷(1);1与2-萘酚在甲苯中回流反应3 d制得新型双氮桥联四酚化合物(2),其结构经1H NMR,IR,MS和元素分析表征。X-射线单晶衍射测定结果表明,1属单斜晶系,空间群C2/c,晶胞参数a=16.145 5(17),b=9.120 6(7),c=17.822 8(18),β=110.831(2)°。

1,2-Bis（8-t-butyl-6-methyl-2H-benzo-[e][1,3]oxazin-3（4H）-yl]ethane（1） in high yield was synthesized from 2-butyl-4-methylphenol,formaldehyde and ethyleneamine in methanol reflux for 2 h.1 reacted with 2-naphthol in toluene reflux for 3 d to obtain a novel bridged tetra（phenol） compound（2）.The structures of 1 and 2 were characterized by 1H NMR,IR,HR-MS and elemental analysis.The results of testing by X-ray single crystal diffraction showed that 1 belongs to monoclinic,space group C 2/c with a=16.145 5（17）,b=9.120 6（7）,c=17.822 8（18）,β=110.831（2）°.
