New phosphorus heterocycles were synthesized using RCM reaction. They were prepared from unsymmetrical or polyfunctional insaturated precursor in 50 to 87% yields solving the problem of possible competitive side reactions. In parallel hydroxyphosphinate scaffolds represent a versatile starting material and could be of great interest for the synthesis of phosphosugar libraries.
使用RCM反应合成了新的磷杂环。它们是由不对称或多官能的不饱和前体制备的,收率为50%至87%,解决了可能的竞争性副反应的问题。平行地,羟基次膦酸盐支架代表了通用的起始材料,并且对于磷酸糖文库的合成可能具有极大的兴趣。
