چکیده
In the title compound, C(5)H(4)BrNO(2), the non-H atoms of the pyrrole ring and the Br atom are approximately coplanar, with an r.m.s. deviation from the best fit plane of 0.025 (6) Å;. The dihedral angle between the plane of the carb-oxy group and this plane is 14.1 (2)°. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules together, forming corrugated sheets parallel to the bc plane.

In the title mol-ecule, C(9)H(6)BrNO(2), the dihedral angle between the -COOH group and the ring system is 6 (4)°. In the crystal, pairs of O-H⋯O hydrogen bonds link the mol-ecules into inversion dimers and these dimers are connected via N-H⋯O hydrogen bonds to form layers parallel to the (-101) plane.
متن کاملAmidation reactions from the direct coupling of metal carboxylate salts with amines.
A general method for the synthesis of amides involving the direct coupling of alkali metal carboxylate salts with amines is described. Amidation of a wide variety of carboxylate salts with either free amines or their ammonium hydrochloride salts can be achieved using HBTU as a coupling agent in combination with Hünig's base. The reaction is highly efficient and is generally complete in as littl...

The title compound, C(19)H(17)NO(3), was synthesized using a tandem annulation reaction between 4-benzoyl-1H-pyrrole-2-carbaldehyde and (E)-ethyl 4-bromo-but-2-enoate under mild conditions. The dihedral angle between the benzene ring and the indolizine ring system is 41.73 (4)°.
متن کاملPalladium-catalyzed C–N and C–O bond formation of N-substituted 4-bromo-7-azaindoles with amides, amines, amino acid esters and phenols
Simple and efficient procedures for palladium-catalyzed cross-coupling reactions of N-substituted 4-bromo-7-azaindole (1H-pyrrole[2,3-b]pyridine), with amides, amines, amino acid esters and phenols through C-N and C-O bond formation have been developed. The C-N cross-coupling reaction of amides, amines and amino acid esters takes place rapidly by using the combination of Xantphos, Cs(2)CO(3), d...
