New ligands derived from 5,5-dimethyldipyrromethane and their corresponding neutral complexes with ZnII and PdII are described. The ligands incorporate either a hexacatenar [H2(1n), n = 1, 10, 12, 14 and 16], te

Synthesis of tetrapyrrane 8 from acetone and pyrrole via one-step condensation was achieved for the first time along with a much-improved yield of the tripyrrane 9. Diborylation of the tetrapyrrane and subsequent 1 + 1 cyclocoupling with 1,2-diiodobenzene following the Suzuki protocol generated novel o-phenylene incorporated macrocycle belonging to the smallest meso-expanded calix[4]pyrrole family. The latter macrocycle displays exclusive turn-on fluorescence sensing of fluoride ion upon complexation via a unique partial cone conformation supported by DFT analysis in acetonitrile solvent.
C-Bridged Bispyrrolidines and Bispiperidines as New Ligands
Stumpf, Tim-Daniel J.,Steinbach, Manfred,H?ltke, Magdalene,Heuger, Gerold,Grasemann, Franka,Fr?hlich, Roland,Schindler, Siegfried,G?ttlich, Richard

The preparation of methylene-bridged C2-symmetric nitrogen-heterocycles as a new class of ligands is described, including methylene-bridged pyridines, quinolones, piperidines and pyrrolidines. These methylene-bridged aromatic systems are obtained via a microwave assisted Ziegler-type reaction. The separation of diastereomers and the application of the copper complexes of these ligands for cyclopropanation reactions proves the applicability of these new types of ligands.
Synthesis and Resolution of a Chiral Diamine: 2,2′-(Propane-2,2-diyl)dipyrrolidine
Kotthaus, Andreas F.,Ballaschk, Frederic,Stakaj, Vjoni,Mohr, Fabian,Kirsch, Stefan F.
, p. 3107 - 3111 (2017/07/12)
A short and practical synthesis of a new chiral dipyrrolidine is presented. The three-step route includes a hydrogenation and a resolution with mandelic acid, which easily affords large quantities of the title compound.
