Osmium-catalyzed aminohydroxylation reactions are accelerated and expanded in scope by the use of olefinic substrates having ionic groups, either anionic or cationic. The use of ionic groups on olefinic substrates also extends the aminohydroxylatable positions of unsaturations to include &agr;,&bgr;, &bgr;,&ggr;, and &ggr;,&dgr; positions, with respect to such ionic groups. A mechanism for the disclosed acceleration and extension is provided.
铂催化的氨羟基化反应通过使用具有离子基团的烯烃底物(无论是阴离子还是阳离子)而得到加速和扩展。在烯烃底物上使用离子基团还将氨羟基化位置扩展到与这些离子基团相关的α,β,β,γ和γ,δ位置。提供了所述加速和扩展的机制。
