Palladium-catalyzed annulation reactions of methyl o-halobenzoates with azabicyclic alkenes: a general protocol for the construction of benzo[c]phenanthridine derivatives was written by Guo, Cui;Huang, Kanglun;Wang, Bo;Xie, Longguang;Xu, Xiaohua. And the article was included in RSC Advances in 2013.Recommanded Product: 653-92-9 This article mentions the following:
The annulation reaction of Me o-halobenzoates with azabicyclic alkenes proceeds efficiently to give the corresponding benzo[c]phenanthridine derivatives in good to excellent yields using a developed base-free methodol. based on our preliminary studies. Thirty-seven application examples validate the compatibility of the present strategy with different groups, particularly with the electron-deficient ones, that are difficult to access using other traditional methods. In addition, annulation reactions with non-sym. azabicyclic alkenes are achieved in high regioselectivity. In the experiment, the researchers used many compounds, for example, Methyl 2-bromo-4-fluorobenzoate (cas: 653-92-9Recommanded Product: 653-92-9).
Methyl 2-bromo-4-fluorobenzoate (cas: 653-92-9) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Recommanded Product: 653-92-9
