Hydantoins Derived from Ketopinic and 4-camphorcarboxylic Acids. French-Ukrainian Journal of Chemistry, 1(1), 23–26.https://ir.library.knu.ua/handle/15071834/25616Diastereospecific formation of hydantoins from ketopinic and 4-camphorcarboxylic acids under Bucherer-Bergs reaction conditions has been investigated. The easiness of this transformation provides a straightforward synthetic pathway to enantiopure conformationally rigid amino acids derivatives, as well as functionalized hydantoins, starting from inexpensive and easily available natural camphor.enHydantoinsketopinic4-camphorcarboxylic acidСтаття
