Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania nowych pochodnych dibenzo[b,f]oksepiny o wzorze 1 gdzie R oznacza podstawiony pierścień 6-metoksy-3-nitro dibenzo[b,f]oksepiny lub 4,4’-dietoksy-1,1’-bifenylu. Powyższy sposób polega na tym że 6-metoksy-3-nitrodibenzo[b,f]oksepinę o wzorze 2 lub 6-metoksy-3-nitrodibenzo[b,f]oksepinę i 4,4’-dietoksy-1,1’-bifenyl rozpuszcza się w chlorometanie i dodaje paraformaldehyd po czym do mieszaniny dodaje się trifluorek boru w eterze dietylowym [BF3•O(C2H5)2], w temperaturze 20-30°C, przy czym trifluorek boru stosuje się z dwukrotnym nadmiarem w stosunku do związku o wzorze 2, a pozostałe reagenty stosuje się w ilościach zbliżonych do stechiometrycznych, całość miesza się w temperaturze pokojowej, przelewa do metanolu a oddzieloną fazę organiczną suszy, zatęża i oczyszcza.The subject of the application is a method for obtaining new dibenzo[b,f]oxepine derivatives of formula 1 where R is a substituted 6-methoxy-3-nitro dibenzo[b,f]oxepine or 4,4'-diethoxy-1,1'-biphenyl ring . The above method consists in the addition of 6-methoxy-3-nitrodibenzo[b,f]oxepine of formula 2 or 6-methoxy-3-nitrodibenzo[b,f]oxepine and 4,4'-diethoxy-1,1'-biphenyl is dissolved in chloromethane and paraformaldehyde is added, then boron trifluoride in diethyl ether [BF3•O(C2H5)2] is added to the mixture at a temperature of 20-30°C, and boron trifluoride is used with a twice excess in relation to the compound with formula 2, and the remaining reagents are used in amounts close to stoichiometric, the whole thing is stirred at room temperature, poured into methanol, and the separated organic phase is dried, concentrated and purified.
