Benz acridines

The only general synthesis in this category is that due to Ullmann, in which 2-chIoro-5-nitrobenzophenone reacts with arylamines at 150-200 °C to give acridines (552) or benz-acridines (553) and (554) (06CB298). The reaction can be done in two stages, heating first with potassium hydroxide to give the 2-aryIamino-5-nitrobenzophenone, with subsequent cyclization by acid. [Pg.470]

A detailed study of the dehydrogenation of 10.1 l-dihydro-5//-benz[6,/]azcpinc (47) over metal oxides at 550 C revealed that cobalt(II) oxide, iron(III) oxide and manganese(III) oxide are effective catalysts (yields 30-40%), but formation of 5//-dibenz[7),/]azepinc (48) is accompanied by ring contraction of the dihydro compound to 9-methylacridine and acridine in 3-20 % yield.111 In contrast, tin(IV) oxide, zinc(II) oxide. chromium(III) oxide, cerium(IV) oxide and magnesium oxide arc less-effective catalysts (7-14% yield) but provide pure 5H-dibenz[b,/]azepine. On the basis of these results, optimum conditions (83 88% selectivity 94-98 % yield) for the formation of the dibenzazepine are proposed which employ a K2CO,/ Mn203/Sn02/Mg0 catalyst (1 7 3 10) at 550 C. [Pg.235]

Mutagenicity data for benz[a]- and benz[c]acridine dlol epoxides and tetrahydroepoxldes reveals a deactivating effect of nitrogen dependent upon its position relative to the epoxide. Benz[a]acridine bay region dlol and tetrahydroepoxldes have significantly reduced mutagenicities relative to their... [Pg.69]

Benzacridine tetrahydroepoxides and did epoxides. The isosteric molecules BA, benz[a]acridine (BaAcr) and benz[c]acridine (BcAcr) and their derivatives provide excellent probes for studying the effect of electronic changes upon biological properties. The... [Pg.84]
