✦ Synopsis


Ring Opening of Methyl 2‐(Trimethylsilylmethyl)cyclopropanecarboxylate

The reactivity of the title compound 5 is compared with that of methyl 2‐siloxycyclopropanecarboxylates. 2. Whereas these are cleaved under various conditions, the less activated derivative 5 undergoes ring opening to yield methyl pentenoate (6a) only with sources of “free” flouride‐like tetra‐n‐butylammonium fluoride.
