The gold(I)-catalyzed oxidative rearrangement of propargyl alcohols provides an efficient and selective route to 1,3-diketones under mild conditions. Pyridine-N-oxides were used as external oxidants with, different from related substrates, no alkylidenecycloalkanones or oxetan-3-ones formed as side-products.
炔丙醇的金(I)催化的氧化重排提供了在温和条件下制备1,3-二酮的有效和选择性途径。吡啶-N-氧化物被用作外部氧化剂,与相关的底物不同,没有形成副产物亚烷基环烷酮或氧杂环丁烷-3-酮。
