A general overview on the chemical and stereochemical behavior of a wide range of stereodefined 2-silyl-1,3-dithianes, -1,3-dioxanes, -1,3-dioxolanes and -1,3-oxathiolanes is reported, when subjected to fluoride ion-induced proto- and carbo-desilylation. Retention of configuration or epimerization appears to depend not only on the kind of the substituents on the aromatic ring, but also on the nature
报告了广泛的立体定义的 2-甲硅烷基-1,3-二噻烷、-1,3-二恶烷、-1,3-二氧杂环戊烷和 -1,3-氧杂硫杂环戊烷的化学和立体化学行为的一般概述,当受到氟离子诱导的原-和碳-脱甲硅烷基化。构型的保留或差向异构化似乎不仅取决于芳环上取代基的种类,还取决于甲硅烷基缩醛中杂原子的性质,导致设想出现游离碳负离子或高价甲硅烷基化物质。图形概要
