Aryl enones undergo selective 1,4-reduction to the correspondingsaturated ketones with two equivalents of tributyltin hydride inthe presence of a wide range of other potentially reducible functionalgroups, including alkyl enone. Additionally during this investigationreductive cyclization of bisenones to give five- and six-memberedcarbocycles via an α,β-coupling process was observed.
在包括亚烷基烯酮在内的多种其他潜在可还原官能团的存在下,芳基烯酮与两当量的三丁基氢化
锡选择性地 1,4-还原为相应的饱和酮。此外,在本研究期间,观察到双烯酮还原环化通过 α,β-偶联过程得到五元和六元碳环。
