Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Urea | HCID 1176 | — |
| Reactant | Hydantoin | HCID 10006 | — |
| Reactant | Octyl isocyanate | HCID 76616 | — |
| Solvent | Ethyl Acetate | HCID 8857 | — |
| Product | HCID 86754453 | HCID 86754453 | — |
Reaction Steps
To a stirred solution of 111 g of aspartic ester (obtained from Bayer #XP 7059) in 200 g of ethyl acetate were added dropwise 75 g of octyl isocyanate (available from Aldrich). After four days the solvent was evaporated to leave the product which was shown by NMR spectroscopy to be a mixture of the urea addition product and the hydantoin cyclization product (ratio=~1:2).
