An efficient and simple source of nitroso reagents and their oxidation reactions are described. The combination of a Lewis acid and a metal nitrite was applied to the oxidation of silyl enol ethers. Amino acid and peptide derivatives were easily accessed through in situ C-C bond cleavage of fully substituted silyl enol ethers upon oxidation.
描述了亚硝基试剂及其氧化反应的有效且简单的来源。路易斯酸和金属亚硝酸盐的组合应用于甲硅烷基烯醇醚的氧化。通过氧化时完全取代的甲硅烷基烯醇醚的原位 CC 键裂解,可以很容易地获得氨基酸和肽衍生物。

Bu3SnH and Ph3SnH in standard free radical reactions, but with the special characteristic that the tin-containing byproducts are easily and very largely removed by mild hydrolysis (LiOH-water-THF or TsOH-water-THF), which converts them into base-soluble (aqueous NaHCO3) materials. The performance of stannane 1 was evaluated for a range of radical reactions involving halides, selenides, Barton-McCombie
易于制备的锡烷1在标准的自由基反应中的行为与常规试剂Bu3SnH和Ph3SnH相似,但具有的特殊特征是,通过温和水解(LiOH-水-THF)可轻松且大量去除含锡副产物或TsOH-水-THF),将其转化为碱溶性(NaHCO3水溶液)。在一系列涉及卤化物,硒化物,Barton-McCombie脱氧和烯炔环化的自由基反应中,评估了锡烷1的性能。在一些情况下,通过1 H NMR监测后处理程序在去除锡中的有效性。
