The rhodium-catalysed reaction of 1-(2-haloaryl)cyclobutanols afforded 3,3-disubstituted α-tetralones. The reaction was applied to the asymmetric synthesis of α-tetralones bearing a chiral quaternary carbon centre at the 3-position, which was otherwise difficult to execute.
铑催化的 1-(2-卤代芳基)
环丁醇反应生成了 3,3-二取代的 δ±-四氢
萘酮。该反应被用于不对称合成在 3 位上带有手性季碳中心的 δ-四氢
萘酮,否则很难实现这一合成。
