, p. 995 - 997 (1997)
Siloxycyclopropane derivatives 3 with a suitable styrene side chain can effectively be ring opened to precursors 2 which undergo reductive ring closure with SmI2 to furnish benzannulated cyclooctanols 1 or lactones 7 derived thereof. Tricyclic
Benzannulated cyclooctanol derivatives by samarium diiodide induced intramolecular carbonyl-alkene coupling - Scope, limitations, stereoselectivity

A series of γ-oxo esters 27-34 was prepared from methyl 2-silyloxycyclopropanecarboxylates 1-9 as key building blocks in a flexible modular synthesis. Their samarium diiodide promoted cyclization to benzannulated cyclooctanol derivatives was systematicall
