Herein we report the use of catalytic amount of scandium(III) triflate or indium(III) chloride (with trimethylsilyl chloride) for the functionalization of endoperoxyacetals through Sakurai or Mukaiyama reactions. These catalysts allow milder and more practical conditions than those previously reported with improvements in scope and reproducibility. This method allows a full catalytic sequence from cyclopropanols to produce desired functionalized 1,2‐dioxolanes.
