The development of a stereospecific hydroxymethylation of alkyl tosylates using an inexpensive, first-row catalyst is described. The transformation proceeds under mild conditions with low pressure to deliver homologated alcohols as products. Chiral, nonracemic β-branched primary alcohols are obtained with high enantiospecificity from easily accessed secondary alkyl substrates. Simple modification of
描述了使用便宜的第一行催化剂开发烷基甲苯磺酸酯的立体有针对性的羟甲基化。该转化在温和条件下以低压进行,以递送作为产物的同系醇。从容易获得的仲烷基底物上获得具有高对映体特异性的手性,非外消旋的β-支链伯醇。将反应体系的简单修改还允许访问α- ð 2醇。这些研究使用阴离子金属羰基催化,以从一氧化碳中获得具有挑战性的羟甲基阴离子的合成等价物。
