Methyl 2-siloxycyclopropanecarboxylates rearrange smoothly and quantitatively to the corresponding silylenolethers (3) by addition of a catalytical amount of iodo trimethylsilane. Scope and limitation of this novelprocess as well as the synthesis of the electron rich diene (10a) are described.

The intramolecularDiels-Alderreactions of a series of ether-tethered trienes 3a-3o show varying selectivities according to the nature of the dienophile-activating group and the presence of substituents in the linking chain. Some tether-cleaving reactions are reported.
