The N1-and N3-cyanohydantoins, a new series of derivatives, were prepared by reaction of the parent hydantoin with a base and a cyanogen halide. Analysis of ir, pmr, and mass spectral data allowed the assignment of ring position-3 to the cyano group in derivatives IIa,b of 1,3-unsubstituted hydantoins. 3-Cyanohydantoins can transfer the cyano substituent to strong nucleophiles via an addition-elimination
