The N-acyl(phenylseleno)oxazolidinone 5 was prepared (85% yield) by treatment of the lithium salt of oxazolidinone with triphosgene, followed by addition of benzeneselenol. Reduction of 5 with n-Bu3SnH/AIBN gave the N- formyloxazolidinone 6 (99%) and reaction with allyltri-n-butylstannane gave 7 (89%). Bimolecular additions to various alkenes using the N-acyl radical derived from oxazolidinone 5 were also studied. Best results were obtained with electron rich olefins, such as enol ether derivatives. Eight such additions are reported, with yields ranging from 51-90%. Two prochiral substrates showed significant levels of diastereoselectivity in reactions with 5/Bu3SnH.
