公开了用 Cu(NO 3 ) 2和 KI 以区域选择性和立体选择性方式对乙烯基环丙烷进行直接硝化,以有效地得到硝基烯烃,其中保留了环丙烷骨架。给定的方法可以扩展到其他乙烯基环以及具有广泛底物范围、良好功能耐受性和高效合成模块化的生物分子衍生物。进一步的转化表明所获得的产品是有机合成中的通用构建块。所提出的离子途径可以解释未接触的小环和反应过程中 KI 的影响。
allylic nitro compounds via cross-metathesis with a new cross-metathesis partner, 3-nitropropene, is reported. The reaction of various terminal olefins with 3-nitropropene, promoted by 5 mol% of standard commercially available ruthenium pre-catalysts in the presence of triphenyl borate, provided the substituted β,γ-nitroolefins in moderate to high yields. These results render the catalytic olefin cross-metathesis
