In control: By controlling the kinetics of alkynylation over aldolization, the challenging asymmetric catalytic alkynylation of acetaldehyde has been realized. The resulting products are attractive synthons which are produced with good to excellent enantiocontrol, and show broad tolerance and applicability, as demonstrated by the synthesis (+)‐tetrahydropyrenophorol.
可控:通过控制炔基化相对于醛醇缩合的动力学,实现了具有挑战性的乙醛不对称催化炔基化。所得产物是有吸引力的合成子,其产生具有良好至优异的对映体控制,并显示出广泛的耐受性和适用性,如合成 (+)-四氢芘佛罗尔所证明的那样。
