Abstract

The title compound, C20H19BrO2S, was synthesized by the cyclization of 1-(4-bromo­phenyl)-4-(3,4-di­methoxy­phenyl)-2,3-di­methyl­butane-1,4-dione with 2,4-bis(4-methoxy­phenyl)-2,4-disulfanyl­ene-1,3,2,4-di­thia­diphosphetane. The dimethoxyphenyl and bromophenyl rings make dihedral angles of 28.4 (3) and 45.0 (3)°, respectively, with the thiophene ring. The bond lengths are unexceptional. [ABSTRACT FROM AUTHOR]

Abstract

The title compound, C26H31NO5S, was synthesized by the palladium-catalyzed coupling reaction of 2-(3-bromo-4-methoxy­phenyl)-3,4-di­methyl-5-(3,4,5-tri­methoxy­phenyl)­thio­phene and morpholine. This mol­ecule is composed of four rings. Two benzene rings are linked by a thio­phene moiety which is planar. The morpholine group has a chair conform­ation. [ABSTRACT FROM AUTHOR]
