✦ Synopsis

NoH Ketimines were prepared from various ketones and ammonia using titanium tetrachloride and were used to form resin-bound ketimines via transimination. They were applied to the solid phase synthesis of hydantoins 1 with four substituent variations using two other building blocks (amino acids and isocyanates). The desired products were obtained with high purity in moderate to good yields in 5 steps.
