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.
已经研究了钛介导的烯丙醇与炔烃的交叉偶联。发现提供立体定义的1,4-二烯或取代的交叉共轭三烯的不同反应途径。简而言之,丙二烯取代在反应路径的确定中起关键作用。
