Solution-Phase Parallel Synthesis of Spirohydantoins. — A library of 168 comof type (VI) with diversity in two positions is synthesized. An anhydrous
32- 141 pounds
one-pot modification of the Strecker reaction is employed to obtain α-amino nitriles
(IV) from piperidinones (I). Subsequent reaction of these nitriles with isocyanates, followed by refluxing under acidic conditions, affords the target compounds in high yields
and purity. — (NIETO, M. J.; PHILIP, A. E.; POUPAERT, J. H.; MCCURDY*, C. R.;
