Functionalized P,C-stereogenic tertiary phosphine oxides were prepared by the addition of (RP)-menthyl phenylphosphine oxide to activated olefins, in high drP and drC, and were isolated in excellent yields. The reaction was readily catalyzed by Ca(OH)2 or occurred with gentle heating. A wide range of substrates, including vinyl ketones, esters, nitriles, and nitro alkenes, can be used in the reaction.
功能化的 P,C-手性叔膦氧化物可通过(R)-薄荷基苯膦氧化物与活性烯烃加成制备,具有高 drP 和 drC,并且以优异的产率分离。该反应可由 Ca(OH)2 容易催化,或在温和加热下进行。反应中可使用包括乙烯基酮、酯、腈和硝基烯烃在内的广泛的底物。
