The synthesis and synthetic utilization of the dimethyleneketene acetal 3 are described in this report. Thermal rearrangement of the methylenecyclopropanone acetal 1 at 150°C gives the dimethyleneketene acetal 3, which serves as a reactive surrogate of th

We report that the O-alkylated enolates of cyclopropanecarboxylates can be prepared from readily available precursors, and that they are extremely reactive, serving as useful surrogates of the elusive parent enolates. The utility is illustrated by the cyc
