Samarium(II) diiodide has been employed to promote the intramolecular cyclization reactions of aldehydes or ketones onto α,β-unsaturated ketones. The cyclization reactions described herein provide a general approach to the syntheses of perhydronaphthalenones with a cis-relationship between the OH at C-5 and the proton or methyl group at C-4a with good diastereoselectivity under mild reaction conditions
io(II)二碘化物已被用于促进醛或酮在分子内环化反应成α,β-不饱和酮。本文所述的环化反应提供了在温和的反应条件下以良好的非对映选择性在C-5处的OH与C-4a处的质子或甲基之间具有顺式关系的全氢萘酮的合成的一般方法。
