Autor: R. M. Simons, D. D. Keane, E.M. Philbin, K. G. Marathe, P. C. Teague, J.P. Doherty, W. I. O'Sullivan

Publikováno v: Tetrahedron Letters. 9:441-445

The four possible isomeric flavindogenide (3-arylideneflavanone) epoxides (type III, IV, V and VI) have been synthesized and their configurations assigned on the basis of chemical and spectroscopic data. Suggested mechanisms for the epoxidation react

The electron-impact promoted fragmentation of aurone epoxides

Autor: W. I. O'Sullivan, A. M. Duffield, B. A. Brady

Publikováno v: Organic Mass Spectrometry. 6:199-210

The mass spectra of six aurone epoxides have been rationalized with the aid of high resolution mass spectrometry and metastable ion evidence. These compounds fragment in a well defined manner and mechanisms are proposed for the formation of their cha
