Titanium-mediated cross-coupling of allenic alcohols with alkynes has been investigated. Divergent reaction pathways were discovered that provide either stereodefined 1,4-dienes or substituted cross-conjugated trienes. In short, allene substitution plays a critical role in the determination of reaction pathway.
已对钛介导的联烯醇与炔烃的交叉偶联反应进行了研究。发现了不同的反应途径,这些途径可提供立体定向的1,4 - 二烯或取代的交叉共轭三烯。简而言之,联烯取代在反应途径的确定中起着关键作用。
