The addition of sodium of sec-benzylphosphine oxide 1a or 1b as well as sodium O-ethyl benzylphosphonite 1c to α,β-unsaturated ketones, followed by intramolecular aldol condensation has been described. The stereochemistry of the reaction and the structure of 2-phospholene-1-oxides 6a–h thus formed is discussed.
已经描述了向α,β-不饱和酮中添加仲苄基氧化膦1a或1b钠以及O-乙基苄基膦酸钠1c,然后进行分子内羟醛缩合。讨论了反应的立体化学和由此形成的2-膦-1-氧化物6a-h的结构。
