The N,N'-dioxide-Cu(I) complexes have been developed to catalyze the addition of nitromethane to N-tosyl aldimines. The aza-Henry reaction proceeds smoothly affording the corresponding nitro amines in good yields with high enantioselectivities. A catalytic cycle is proposed to explain the origin of reactivity.
已开发出N,N'-二氧化物-铜(I)配合物用于催化硝基甲烷与N-甲苯磺酰基醛亚胺的加成反应。氮杂亨利反应顺利进行,以高对映选择性高产率得到相应的硝基胺。提出了一个催化循环来解释反应活性的起源。
