Reactivity of bromoselenophenes in palladium-catalyzed direct arylations
The reactivity of 2-bromo- and 2,5-dibromoselenophenes in Pd-catalyzed direct heteroarylation was investigated. From 2-bromoselenophene, only the most reactive heteroarenes could be employed to prepare 2-heteroarylated selenophenes; whereas, 2,5-dibromoselenophene generally gave 2,5-di(heteroarylated) selenophenes in high yields using both thiazole and thiophene derivatives. Moreover, sequentia...
متن کاملPd-catalysed [3 + 3] annelations in the stereoselective synthesis of indolizidines
A [3 + 3] annelation of enantiomerically pure aziridine 7 provides the functionalised piperidine 8 that can be elaborated to the indolizidine skeleton in only 4 steps with good stereocontrol.
متن کاملDibenzoatobis[3-(pyrrol-1-ylmethyl)pyridine]zinc(II)
In the title compound, [Zn(C(7)H(5)O(2))(2)(C(10)H(10)N(2))(2)], the Zn(II) ion, located on a twofold axis, is coordinated by two N atoms from two 3-(pyrrol-1-ylmeth-yl)pyridine ligands and two O atoms from two benzoate ligands in a distorted tetra-hedral geometry. The pyridine and the pyrrole rings are nearly perpendicular to each other, making a dihedral angle of 84.83 (7)°.
متن کامل3-Benzamido-1-benzoyl-1H-pyrrol-2(5H)-one
In the title compound, C(18)H(14)N(2)O(3), one of the phenyl rings is almost coplanar with the pyrrole ring [dihedral angle = 2.56 (14)°], whereas the other one is tilted by 63.01 (6)° with respect to the pyrrole ring. Since the NH group is shielded from possible acceptors, this group is not involved in hydrogen bonding.
متن کاملRadical C-H arylations of (hetero)arenes catalysed by gallic acid.
Gallic acid efficiently catalyses radical arylations in water-acetone at room temperature. This methodology proved to be versatile and scalable. Therefore, it constitutes a greener alternative to arylation. Moreover, considering that gallic acid is an abundant vegetable tannin, this work also unleashes an alternative method for the reutilisation of bio-wastes.
