Abstract

Abstract We have shown that sulfuryl chloride is an efficient reagent for the conversion of 2- oxazolidinone into the dichloro derivative, N-acetyl-4, 5-dichloro-2-oxazolidinone. Subsequent Zn/AcOH reductive dehalogenation of this trans-dichloride gives N-acetyl-2- oxazolone. The dichloride was previously reported as an undesired side product in the preparation of N-acetyl-2-oxazolone from the monochloro oxazolidinone. In our hands, the ...
