Silylphosphanes 3 and 4 gave 1,4-additions with the O=C-C=C moiety of oxazolones 1a-e and 2a-f to afford the adducts 5–8. Oxidation or sulfuration of 5–8 followed by hydrolysis led to oxyphosphorus (or thiophosphorus) amido-acids 9–11 and 15, 19, 20 respectively. A great difference was observed in the behaviour of thiophosphane oxides 16 (R = Me) and 17(R = Ph) toward hydrolysis: 16 led directly to
甲硅烷基膦 3 和 4 与恶唑酮 1a-e 和 2a-f 的 O=CC=C 部分发生 1,4-加成,得到加合物 5-8。5-8 的氧化或硫化,然后水解,分别生成含氧磷(或硫代磷)酰胺酸 9-11 和 15、19、20。观察到硫代磷烷氧化物 16 (R = Me) 和 17 (R = Ph) 的水解行为存在很大差异:16 通过打开内酯环直接导致酰胺酸 19,而从 17 开始,杂环中间体18个可以隔离。
