Description
技术领域
本发明涉及一种合成胺硫氰基类化合物的方法,尤其涉及一种可见光驱动合成3-胺基-2-硫氰基-α,β-不饱和化合物的方法。
背景技术
多取代烯烃在有机合成中具有极为重要的应用价值,烯烃上引入新的官能团是近百年来化学工作者孜孜不倦的追求,各种合成方法日新月异。3-胺基-2-硫氰基-α,β-不饱和化合物是一种重要的合成中间体,包含了胺基,硫氰基,酯基(羰基,磷脂,氰基,硫酯)等多官能团烯烃。尤其是硫氰基可以转换成不同的官能团,如SCF3,SCF2H,硫代磷酸酯,四氮唑,硫醚,不对称的二硫醚等含硫化合物。当今化学界的研究热门方向不对称化学中也具有潜在的应用价值,合成多样的手性化合物。同时也是合成一些重要杂环的前体,例如多官能团的吡啶酮和2-胺基噻唑类化合物等。
3-胺基-2-硫氰基-α,β-不饱和化合物的独特骨架结构,增添其在有机合成中的重要应用。但是其合成方法却非常局限,极大地限制了应用性。在二十世纪末Kyongtae Kim等报道了以烯胺酯为原料,4-Chloro-5H-1,2,3-dithiazol-5-one为硫氰基试剂得到了胺硫氰基化的产物。直到2004年,Xian Huang等报道了以Alkenyl Iodonium Salts为原料,KSCN为亲核试剂,得到了胺硫氰基的产物。此外曾有披露使用电催化的方法实现了胺硫氰基化合物的合成,但其合成方法还存在很大缺陷,起始原料预官能团化,复杂的硫氰基试剂,产率低,同时生成有毒的副产物。当今绿色化学的发展趋势下,此类反应明显不能满足需求。发展一种条件温和,高原子效率的方法来弥补这一缺陷势在必行。
