In the title compound, C(18)H(11)NO, the carbazole and benzofuran rings are almost co-planar, making a dihedral angle of 3.31 (3)°. The crystal structure is stabilized by weak C-H⋯π inter-actions.

In the title compound, C(20)H(12)BrFO(2)S, the O atom and the phenyl group of the phenyl-sulfinyl substituent lie on opposite sides of the plane through the benzofuran fragment; the phenyl ring is nearly perpendicular to this plane [dihedral angle = 86.98 (6)°]. The 4-bromo-phenyl ring is rotated slightly out of the benzofuran plane, making a dihedral angle of 1.56 (8)°. The crystal structure f...

The domino three-component coupling reaction of arynes with DMF and active methylenes or methines was studied as a highly efficient method for preparing heterocycles. Coumarin derivative 5 was formed when diethyl malonate (2) or α-bromomalonate (3) were used as a C2-unit. In contrast, dihydrobenzofurans 7a and 7b were obtained by using α-chloroenolates generated from α-chloromalonates 4a and 4b...

Addition of fluoroarenes, fluoroalkanes or benzofuran to [{(2,6-(i)Pr2C6H3NCMe)2CH}Al] results in facile oxidative addition of either a C-F or C-O bond to the Al(I) centre.

In this study, a series of novel benzofuran-based 1,2,4-triazole derivatives (10a–e) were synthesized and evaluated for their inhibitory potential against acetylcholinesterase (AChE) bacterial strains (E. coli B. subtilis). Preliminary results revealed that almost all assayed compounds displayed promising efficacy AChE, while compound 10d was found to be highly potent inhibitor AChE. Similarly,...

The title compound, C(22)H(15)BrO(3)S, crystallizes with four mol-ecules in the asymmetric unit. The 4-bromo-phenyl rings are rotated out of the benzofuran planes, with dihedral angles for the four mol-ecules of 20.8 (2), 17.8 (2), 23.5 (4) and 23.9 (4)°. The dihedral angles between the 3,4-methyl-ene-dioxy-phenyl ring and the benzofuran plane are 13.5 (2), 7.1 (2), 18.6 (3) and 14.2 (3)° in th...

The title compound, C(16)H(13)IO(3)S, was prepared by the oxidation of 5-iodo-2,7-dimethyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 76.31 (8)° with the plane of the benzofuran fragment. The crystal structure is stabilized by aromatic π-π inter-actions between the furan and benzene rings of neighbouring mol-ecules, and between th...

The title compound, C(18)H(16)O(3)S, crystallizes with two symmetry-independent mol-ecules in the asymmetric unit. The phenyl rings are rotated out of the benzofuran planes, making dihedral angles of 43.38 (7) and 56.13 (6)° in the two mol-ecules. The carboxyl groups are involved in inversion-related inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. Th...

A new series of (benzofuran-2-yl)-1-phenyl-1H-pyrazol-4-yl) pyrimidine derivatives were synthesized from 3-(benzofuran-2-yl)-1-phenyl-1H-pyrazol-4-carbaldehyde (1) through different routes of cyclocondensation reactions. Condensation of 1 with active methylene compounds afforded compounds 2-8. The cyclization of 2 with chloroacetic acid, ortho substituted benzoic acid and/or ethanolamine gave c...

In the title compound {systematic name: (S)-3-[(aminocar-bonyl)diphenylmethyl]-1-[2-(2,3-di-hy-dro-benzofuran-5-yl)ethyl]pyrrolidinium bromide}, C(28)H(31)N(2)O(2) (+)·Br(-), the pyrrolidine rings adopts an envelope conformation. The two phenyl rings make a dihedral angle of 72.5 (1)°. The four coplanar atoms of the pyrrolidine ring makes dihedral angles of 33.1 (2) and 82.8 (2)° with the two p...
