A new tandem isomerisation/cyclisation of α-methallyloxy carboxylic acids leading to substituted 1,3-dioxolan-4-ones in 60–70 % yields was catalysed by Cu(OTf)2 or Al(OTf)3. Extension to the synthesis of oxathiolanones and oxathianones is also described. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
Cu(OTf)2 或 Al(OTf)3 催化了一种新的 α-甲基烯丙氧基羧酸串联异构化/环化,产生了 60-70% 的产率取代的 1,3-二氧戊环-4-酮。还描述了对氧杂硫杂环戊烷酮和氧杂硫杂酮的合成的扩展。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
