and treated with lBuCl (1.18 g, 12.8 mmol) directly after filtration. The mixture was stirred at room temperature for 12 h before the orange solution was evaporated to dryness. Recrystallization of the residue from toluene (ca. 30 mL) affords a yellow crystalline powder (2.50 g, 40%). which decompos
A wide variety of radical precursors having the structure of "/-oxygenated-ct,13-unsaturated sulfone (substrates 1-4) have been prepared. Both 5-hexenyl and 6-heptenyl radicals, generated by reaction of substrates 1-4 with Bu3SnH/AIBN, underwent an efficient cyclizatlon via intramolecular addition t
