and phenyl-methyl-substituted 4-silacyclohexyl tosylates (IcId) were compared with isosteric 4,4-disubstituted cyclohexyl tosylates. The rates of acetolysis of the silatosylates were three to five times greater than those of the carbocyclic analogs. With the exception of Ia, which largely fragmented to di-4-pentenyltetramethyldisiloxane, the acetolysis products of compounds I were acetates and olefins

A simple and efficient two-step method for the synthesis of silacyclohexanones starting from bis(bromoethylsilanes) using TosMIC is presented. The prepared silacyclohexanones were transformed to nine different heterocycles with silicon incorporation. In addition, the developed methodology was used for the synthesis of a sila analogue of the HDAC6 inhibitor tubastatin A.
提出了一种使用 TosMIC以双(溴乙基硅烷)为原料合成硅杂环己酮的简单而有效的两步法。将制备的硅杂环己酮转化为九种不同的硅掺入杂环。此外,所开发的方法还用于合成 HDAC6 抑制剂图巴他汀 A 的 sila 类似物。
