The reaction of α,b-chalcone ditosylates 3 with potassium hydroxide in suitable conditions leads to 1,2-aryl shift and carbon-carbon bond cleavage, thereby providing a novel route for the synthesis of 1,2-diarylethan-1-ones 4 and 1,2-diaryl-3,3-dimethoxy propan-1-ones 5.
α,β-二茂酮二托烯3与氢氧化钾在适当条件下反应,导致1,2-芳基位移和碳-碳键断裂,从而提供了一条合成1,2-二芳烯基-1-酮4和1,2-二芳基-3,3-二甲氧基丙-1-酮5的新路线。
