Ma. Eugenia Ochoa Becerra, Susana Rojas-Lima, Herbert Höpfl, Patricia Rodríguez, Dolores Castillo, Rosa Luisa Santillán Baca and José Norberto Farfán García. "Facile synthesis of 1,3,6-oxadiazepines from 2,2'-(1,2-ethanediyldiimino)bisfenols. Tetrahedron, 57, 55-64 (2001). DOI:


A useful sequence of reactions for the syntheses of a variety of heterocyclic systems including an oxadiazepine ring is described. The key step involves the condensation of substituted 2,2?-(1,2-ethanediyldiimino)bisphenols with ethanedial to provide stereoselectively the 6a,7a-trans-6,6a,7a,8,15,16-hexahydro[1,4]benzoxazine[4?,3?:6,7][1,3,6]oxadiazepino[2,3-c][1,4]-benzoxazine-6,8-diol framework, as established by X-ray diffraction analyses.
