Samarium diiodide mediated 6- exo cyclisations of methylenecyclopropyl ketones

Graphic 6- exo Cyclisations of methylenecyclopropyl ketones, mediated by samarium diiodide, have been investigated with a series of substrates. The efficiency of the cyclisations are highly dependent on the stereochemistry of the cyclisation precursor.
