Steroidal quinoxalines

Steroidal quinoxalines of the type 248 have been synthesized,240 and the quinoxaline ring has also been incorporated into the C and D ring of steroids to give 11,14-diazaestrapentaenes (e.g., 249).241... [Pg.424]

Makhluf J. Haddadin was born in Main, Jordan. He holds B.S. and M.S. degrees (Professor C. H. Issidorides) from the American University of Beirut and a Ph.D. degree from the University of Colorado, USA (Professor A. Hassner). He was a research fellow at Harvard University (Professor L. F. Fieser). The art of heterocyclic chemistry has been his main hobby as he worked on heterocyclic steroids, isobenzofurans, isoindoles, quinoxaline 1,4-dioxides (the Beirut reaction), pyridazines, tetrazines, 277-indazoles, and other heterocycles. He rejoined his alma mater in 1964 and currently serves as professor of chemistry. He was vice-president for academic affairs (1987-99). [Pg.319]
