A new carbonylation reaction, namely “triple carbonylation” of olefins catalysed by cationic palladium complexes to substituted 2-oxoglutarates, has been developed. Even though the chemoselectivity is not high, this reaction allows a one-step synthesis of substituted 2-oxoglutarates with fair to excellent enantioselectivity (enantiomeric excess up to 92%). The reaction is completely regioselective
已经开发出一种新的羰基化反应,即通过阳离子钯络合物催化的烯烃的“三羰基化”反应生成取代的2-氧戊二酸酯。即使化学选择性不高,该反应也可以一步合成具有良好的对映选择性(对映体过量高达92%)的取代的2-氧戊二酸酯。该反应对苯乙烯是完全区域选择性的,而与脂族烯烃形成两种区域异构体。
