Patent number: 5304647Abstract: A method of preparation of substituted halogenodiazines which are useful as intermediates in the synthesis of novel unfused heterobicyclic compounds, and the products thereof.The reaction consists of the addition of an organolithium reagent with subsequent dehydrogenation of the addition product. The reaction takes place in one reaction vessel, without isolation of the substituted halogenodihydrodiazine intermediate. The reactions proceed at moderate temperature and in a short amount of time, which decreases the probability of side reactions and increases yield. Furthermore, the workup step is conducted under two-phase conditions to prevent hydrolysis of the substituted halogenodiazine to a substituted hydroxydiazine. The method is easy, efficient and results in a high yield of product.Type: GrantFiled: August 24, 1990Date of Patent: April 19, 1994Assignee: Georgia State University Foundation, Inc.Inventors: Lucjan Strekowski, Maria Mokrosz, Donald B.
