Metal-Free Synthesis of N-Aryl-Substituted Azacycles from Cyclic Ethers Using POCl3

A facile method for the synthesis of N-aryl-substituted azacycles from arylamines and cyclic ethers has been developed. In this study, arylamines were treated with cyclic ethers in the presence of POCl3 and DBU to provide five- A nd six-membered azacycles. Using this method, various azacycloalkanes, isoindolines, and tetrahydroisoquinolines were prepared in high yields. This synthetic method offers an efficient approach to the production of azacycles from cyclic ethers.

Expanding the Medicinal Chemist Toolbox: Comparing Seven C(sp2)-C(sp3) Cross-Coupling Methods by Library Synthesis

Despite recent advances in the field of C(sp2)-C(sp3) cross-couplings and the accompanying increase in publications, it can be hard to determine which method is appropriate for a given reaction when using the highly functionalized intermediates prevalent in medicinal chemistry. Thus a study was done comparing the ability of seven methods to directly install a diverse set of alkyl groups on “drug-like” aryl structures via parallel library synthesis. Each method showed substrates that it excelled at coupling compared with the other methods. When analyzing the reactions run across all of the methods, a reaction success rate of 50% was achieved. Whereas this is promising, there are still gaps in the scope of direct C(sp2)-C(sp3) coupling methods, like tertiary group installation. The results reported herein should be used to inform future syntheses, assess reaction scope, and encourage medicinal chemists to expand their synthetic toolbox.

Porous chitosan microspheres supported-palladium catalyst for the C-N cross-coupling of aryl halides with secondary amines

Porous chitosan microspheres-supported palladium catalysed the amination of aryl halides with a wide variety of secondary amines to yield the corresponding cross-coupling products under aerobic conditions. Both aryl bromides and iodides gave good to excellent yields of N,N-disubstituted anilines. The procedure can tolerate common functional groups such as chloro, methoxyl and nitro. The heterogeneous catalysis is efficienct and the catalyst could be recycled seven times without obvious decreased conversion.

New phosphorus sulfide cyanides and amides: Assigning phosphorus NMR spectra of polycyclic compounds using low-level ab initio calculations of shieldings

Oxidation of P4S3 with ICN gives exo,exo- and endo,exo-beta-P4S3I2, -beta-P4S3(CN)2, and -beta-P4S3I(CN) as initial products. Ab initio GIAO calculations of NMR shieldings at the RHF/3-21G* level are sufficient to assign the spectrum of endo,exo-beta-P4S3(CN)2 and to confirm the identity of the observed endo,exo-beta-P4S3I(CN), which has iodine rather than cyanide in the hindered endo position. Reaction of enantiomerically pure (S)-1-phenyltetrahydroisoquinoline with exo,exo-beta-P4S3I2 gives an exo,exo-diamide in which the Cs symmetry of the beta-P4S3 cage is lost. The two amido groups, planar at nitrogen, are each capable of two orientations, giving four P-N bond rotamers at 183 K. The 31P NMR spectra of three of these have been fitted, and assigned to particular rotamers by ab initio shielding calculations.

1,4-Benzodiazepines as inhibitors of respiratory syncytial virus

Respiratory syncytial virus (RSV) is the cause of one-fifth of all lower respiratory tract infections worldwide and is increasingly being recognized as a serious threat to patient groups with poorly functioning immune systems. Our approach to finding a novel inhibitor of this virus was to screen a 20 000-member diverse library in a whole cell XTT assay. Parallel assays were carried out in the absence of virus in order to quantify any associated cell toxicity. This identified 100 compounds with IC50’s less than 50 muM. A-33903 (18), a 1,4-benzodiazepine analogue, was chosen as the starting point for lead optimization. This molecule was moderately active and demonstrated good pharmacokinetic properties. The most potent compounds identified from this work were A-58568 (47), A-58569 (44), and A-62066 (46), where modifications to the aromatic substitution enhanced potency, and A-58175 (42), where the amide linker was modified.

Phosphoryl chloride-mediated solvent-free synthesis of N-aryl-substituted azacycles from arylamines and cyclic ethers

A solvent- and metal-free protocol for preparation of N-aryl substituted azacycles from arylamines and cyclic ethers is described. In this method, the combination of POCl3 and DBU is crucial for conversion of arylamines and cyclic ethers to five- and six-membered azacycles. Without solvent, a variety of N-aryl-substituted, five-membered azacycles (pyrrolidines, 2-methylpyrrolidines, and piperidine) and six-membered azacycles (isoindolines and tetrahydroisoquinolines) are synthesized in high yields. This green method provides a sustainable and efficient approach for the preparation of azacycles from various cyclic ethers.

Breaking Symmetry: Engineering Single-Chain Dimeric Streptavidin as Host for Artificial Metalloenzymes

The biotin-streptavidin technology has been extensively exploited to engineer artificial metalloenzymes (ArMs) that catalyze a dozen different reactions. Despite its versatility, the homotetrameric nature of streptavidin (Sav) and the noncooperative binding of biotinylated cofactors impose two limitations on the genetic optimization of ArMs: (i) point mutations are reflected in all four subunits of Sav, and (ii) the noncooperative binding of biotinylated cofactors to Sav may lead to an erosion in the catalytic performance, depending on the cofactor:biotin-binding site ratio. To address these challenges, we report on our efforts to engineer a (monovalent) single-chain dimeric streptavidin (scdSav) as scaffold for Sav-based ArMs. The versatility of scdSav as host protein is highlighted for the asymmetric transfer hydrogenation of prochiral imines using [Cp*Ir(biot-p-L)Cl] as cofactor. By capitalizing on a more precise genetic fine-tuning of the biotin-binding vestibule, unrivaled levels of activity and selectivity were achieved for the reduction of challenging prochiral imines. Comparison of the saturation kinetic data and X-ray structures of [Cp*Ir(biot-p-L)Cl]¡¤scdSav with a structurally related [Cp*Ir(biot-p-L)Cl]¡¤monovalent scdSav highlights the advantages of the presence of a single biotinylated cofactor precisely localized within the biotin-binding vestibule of the monovalent scdSav. The practicality of scdSav-based ArMs was illustrated for the reduction of the salsolidine precursor (500 mM) to afford (R)-salsolidine in 90% ee and >17 ?000 TONs. Monovalent scdSav thus provides a versatile scaffold to evolve more efficient ArMs for in vivo catalysis and large-scale applications.
