A highly regioselective, one-step dehydrogenation of α-substituted cyclic ketones in the presence of 2,3-dichlorobenzo-5,6-dicyano-1,4-benzoquinone is described. The reaction proceeds via phosphoric acid-based enol catalysis and provides access to several α-aryl and α-alkyl substituted α,β-unsaturated ketones.
描述了在 2,3-二氯苯并-5,6-二氰基-1,4-苯醌存在下,α-取代环酮的高度区域选择性一步脱氢。该反应通过基于磷酸的烯醇催化进行,并提供多种 α-芳基和 α-烷基取代的 α,β-不饱和酮。
