We have found that refluxing 2-iminooxazolidines Ia-c for 5-15 min in aqueous acetic acid readily causes hydrolytic cleavage of the C=N bond and formation of the 2-oxazolidines IIa,c (R 2 = COCH3) in 75~80% yield. Under the same conditions using hydrochloric acid the C=N bond is cleaved only in the
