[reaction--see text] A new strategy for the synthesis of 2,3-disubstituted cyclopentenones emerges from two key reactions-the ruthenium-catalyzed three-component coupling of an equivalent of HBr, an alkyne, and a vinyl ketone and the Ni-Cr Barbier type reaction. As a result, these important structures are readily accessed from an alkyne and a vinyl ketone (which derive directly from carboxylic acids)
[反应-见正文]由两个关键反应产生了一种合成2,3-二取代的环戊烯酮的新策略-钌催化的三组分相当于HBr,炔烃和乙烯基酮与Ni的三组分偶联-Cr Barbier型反应。结果,很容易从炔烃和乙烯基酮(它们直接衍生自羧酸)获得这些重要的结构。四氢二烯酮B和罗沙前列醇的合成说明了该新策略。
