Samarium(II)-mediated reactions of gamma,delta-unsaturated ketones. Cyclization and fragmentation processes

Author(s): T. K. Hutton, K. Muir, D. J. Procter

Abstract:
[GRAPHICS] On treatment with samarium(II) iodide, gamma,delta-unsaturated ketones undergo very different processes depending upon the nature of the reaction conditions. Employing samarium(II) iodide and MeOH, functionalized syn-cyclopentanol products are obtained stereoselectively. Mechanistic studies suggest that this cyclization occurs via a sequential reduction/intramolecular aldol reaction. With samarium(II) iodide and HMPA, products of a 4-exo-trig cyclization and of an interesting fragmentation reaction are observed.
