The evolution of methods for carbonyl allylation and crotylation of alcohol proelectrophiles culminating in the design of iodide-bound ruthenium-JOSIPHOS catalysts is prefaced by a brief historical perspective on asymmetric carbonyl allylation and its relevance to polyketide construction. Using gaseous allene or butadiene as precursors to allyl- or crotylruthenium nucleophiles, respectively, new capabilities for carbonyl allylation and crotylation have been unlocked, including stereo- and site-selective methods for the allylation and crotylation of 1,3-diols and related polyols.
醇亲电试剂羰基烯丙基化和巴豆酰化方法的发展最终促成了碘结合钌-JOSIPHOS催化剂的设计,在此之前先简要回顾了不对称羰基烯丙基化及其与聚酮化合物构建的相关性。分别使用气态丙二烯或丁二烯作为烯丙基钌或巴豆基钌亲核试剂的前体,羰基烯丙基化和巴豆酰化展现出了新的能力,包括1,3-二醇及相关多元醇烯丙基化和巴豆酰化的立体和位点选择性方法。
