oxidative conditions and the corresponding β-keto-sulfone compounds were obtained in moderate to good yields. Importantly, this transformation offered the first protocol for Csp3S bond formation by oxidative Csp2Csp2 bond cleavage in one step.
已经开发了新颖的TBAI催化的容易获得的N,N-二甲基亚
氨基酮与磺酰
肼的自由基磺酰化,以提供官能化的β-酮砜。在目前的氧化条件下,各种官能团的耐受性良好,并且以中等至良好的产率获得了相应的β-酮砜化合物。重要的是,该转化为通过一步氧化Csp 2 Csp 2键的裂解形成Csp 3 S键提供了第一个方案。
