Radical-Type Cyclization of Dienes, IX. - On the Stereoselectivity of the Radical 4-exo-trig-Cyclization of Optically Active Ethyl (2E)-6-Oxohex-2-enoates with Samarium(II) Iodide

Ethyl (5R,2E)-5-(benzyloxy)-4,4-dimethyl-6-oxohex-2-enoate (9) was prepared from (R)-(-)-pantolactone (3) by a series of straightforward reactions.The reaction of 9 with samarium(II) iodide produces enantiomerically pure ethyl (1S,3R,4R)-(-)-3-(benzyloxy
