Popis: | On thermal treatment of the aziridines 5a - f intramolecular cycloaddition reactions of the intermediate azomethine ylides 6 result in the formation of the metacyclophanes 7 - 9 . For 7a and 7b the conformational barriers areestimated to be approximately 20 and 12 kcal/mol, respectively. |
