A metal-free oxidative cyclization of N-Boc-acrylamides with (diacetoxyiodo)benzene in acetic acid produced 5,5-disubstituted oxazolidine-2,4-diones with the formation of a C–O bond in moderate to excellent yields. In addition, the reaction was diastereospecific with N-Boc-2,3-dimethylacrylamides and proceeded with phenyl migration in the case of an N-Boc-2-phenylacrylamide to generate a 5-acetoxy
N -Boc-丙烯酰胺与(二乙酰氧基碘)苯在乙酸中的无金属氧化环化反应生成5,5-二取代的恶唑烷-2,4-二酮,并以中等至极好的收率形成C–O键。另外,该反应与N -Boc-2,3-二甲基丙烯酰胺是非对映特异性的,并且在N -Boc-2-苯基丙烯酰胺的情况下进行苯基迁移以生成5-乙酰氧基-5-苄基恶唑烷-2,4-二酮。 。
