The rhodium (I) catalysed tandem hydrosilylation-intramolecular aldol reaction provides a simple strategy for construction of a range of usefully functionalised five-membered rings from readily prepared 6-oxo-2-hexenoates in good yield and with good to excellent stereoselectivity. A series of silanes and rhodium catalysts have been investigated. Stereoselectivity proved to be highly dependant on the
铑(I)催化的串联氢化硅烷化-分子内醇醛缩合反应提供了一种简单的策略,可从容易制备的6-氧代-2-己烯酸酯以高收率和良好至极好的立体选择性构建一系列有用的官能化五元环。已经研究了一系列硅烷和铑催化剂。立体选择性被证明高度依赖于催化剂以及母体底物的取代模式。还已经评估了这种方法用于合成更大环尺寸的扩展。
