摘　　要：5-苄基-4-叔丁基-2-氨基噻唑与芳香醛缩合制备了1 1种5-苄基-4-叔丁基-2-苄亚氨基噻唑.结构经1H NMR和元素分析确证,并用单晶X-射线衍射测定了化合物Ⅰc的晶体结构.化合物Ⅰc晶体属单斜晶系,空间群为P21/n,晶胞参数为:a=1.43753(11)nm,b=0.98665(8)nm,c=1.46565(12)nm,β=114.2560(10)°;Z=4,V=1.8953(3)nm3,Dc=1.349 g/cm3,F(000)=808,R1=0.0507,wR2=0.1163,S=1.03.体外筛选结果表明,化合物Ⅰb,Ⅰk在10μmol/L浓度下对COX-2的抑制率超过50%.Eleven new 5 .benzy1-4 --tert -butyl-2 .benzyliminothiazoles were synthesized through the reaction of 5 -arylmethyl-4-tert-butylthiazol-2-amine and aromatic aldehyde. Their structures were established with NMR spectra and elemental analysis. The crystal structure of compound I e has been determined by X-ray dif- fraction analysis. The compound I e crystal belonges to monoclinic system with space group P2 1/ n and cell parameters： a=1.43753（11）nm,b=0.98665（8）nm,c=1.46565（12）nm,p=114.2560（10）°;Z=4,V=1.8953（3）mm3,Dc=1.349g/cm3,F（000）=808,R1=0.0507,ωR2=0.1163,S=1.03. Biological tests showed that compound I b, I k exhibited ≥50 % inhibition rate against COX-2 in vitro.
