Radical C-H functionalization to construct heterocyclic compounds

Heterocyclic compounds are widely present in natural products, pharmaceuticals and bioactive molecules. Thus, organic and pharmaceutical chemists have been making extensive efforts to construct those heterocyclic frameworks through developing versatile and efficient synthetic strategies. The direct C-H functionalization via the radical pathway has emerged as a promising and dramatic approach towards heterocycles with high atom- and step-economy. Heterocyclic compounds such as coumarins, furans, benzofurans, xanthones, benzothiazoles, indoles, indolines, oxindoles, quinolines, isoquinolines, quinoxaline, and phenanthridines have been successfully synthesized by C-H functionalization through the radical pathway. In this review, recent advances on radical C-H functionalization to construct heterocyclic compounds are highlighted with discussions.

Design and SAR of novel potassium channel openers targeted for urge urinary incontinence. 1. N-cyanoguanidine bioisosteres possessing in vive bladder selectivity

A structurally novel series of adenosine 5′-triphosphate-sensitive potassium (K(ATP)) channel openers is described. As part of our efforts directed toward identifying novel, bladder-selective potassium channel openers (KCOs) targeted for urge urinary incontinence (UUI), we found that bioisosteric replacement of the N-cyanoguanidine moiety of pinacidil (1, Figure 1) with a diaminocyclobutenedione template afforded squaric acid analogue 2, the prototype of a novel series of K(ATP) channel openers with unique selectivity for bladder smooth muscle in vive. Further modification of the heterocyclic ring to give substituted aryl derivatives (3) afforded potent KCOs that possessed the desired detrusor selectivity when administered orally. The effects of these potassium channel agonists on bladder contractile function was studied in vitro using isolated rat detrusor strips. Potent relaxants were evaluated in vive in a rat model of bladder instability. Lead compounds were evaluated concomitantly in normotensive rats for their effects on mean arterial blood pressure (MAP) and heart rate as a measure of in vive bladder selectivity. (R)-4-[3,4-Dioxo-2-(1,2,2-trimethyl- propylamino)-cyclobut-1-enyalphamino]-3-ethyl-benzonitrile (79) met our potency and selectivity criteria and represents an attractive development candidate for the treatment of UUI. Electrophysiological studies using isolated rat bladder detrusor myocytes have demonstrated that compound 79 produces significant hyperpolarization which is glyburide-reversed, thus consistent with the activation of K(ATP). The design, synthesis, structure-activity relationships (SAR), and pharmacological activity associated with this series of novel KCOs will be discussed.

Copper(I)-Catalyzed Tandem One-Pot Synthesis of 2-Arylthiobenzothiazoles and 2-Arylthiobenzoxazoles in Water

An efficient tandem process for the preparation of 2-arylthiobenzothiazoles has been developed. By condensation of 2-aminobenzenethiol with tetramethylthiuram disulfide (TMTD), 2-mercaptobenzothiazoles was in situ generated, which susequently underwent coupling with iodobenzenes to give the desired 2-arylthiobenzothiazoles fluently in a one-pot manner. This method can also be used for the synthesis of 2-arylthiobenzoxazoles. Inexpensive metal catalyst and ligand, mild reaction temperature, and water as solvent make this protocol practically valuable and useful in organic synthesis.

Alkylation of Aromatic Amines with Trialkyl Amines Catalyzed by a Defined Iridium Complex with a 2-Hydroxypyridylmethylene Fragment

Six Cp?Ir complexes containing NN-bitentate chelate ligands [Cp?IrCl(C5H4CH2C5H3OH)][Cl] (1), [Cp?IrCl(C5H4CH2C5H3O)] (2), [Cp?IrCl(C5H4C5H3OH)] [Cl] (3), [Cp?IrCl(C5H4CH2C5H4)][Cl] (4), [Cp?IrCl(CH3OC5H3CH2C5H3OCH3)][Cl] (5), and [Cp?IrCl(CH3OC5H3CH2C5H3OH)][Cl] (6) were synthesized and characterized. Complex 1 could be transformed to 2 when reacted with NaOtBu or NEt3 via -OH deprotonation. These six complexes were tested as catalysts for mono-N-alkylation of amines with trialkyl amines, and complex 1 exhibited highest activity. The coupling reactions proceed under air condition, with 1 mol % catalyst loading without extra base in methanol at 120 C and can be further accelerated by adding NR3¡¤HCl.

Synthesis and reactivity of halogeno-difluoromethyl aromatics and heterocycles: Application to the synthesis of gem-difluorinated bioactive compounds

In an effort to prepare new fluorine-containing compounds which are active against HIV, and based on the electrochemical reduction of a series of bromodifluoromethyl compounds, the tetrakis(dimethylamino)ethylene (TDAE) was found to be an effective reductant of the 2-(bromodifluoromethyl)benzoxazole 1 and of the 5-(bromodifluoromethyl)-3-phenyl-1,2,4-oxadiazole 3. A stepwise electron transfer with a difluoromethyl radical as intermediate is assumed to take place in this reaction. Under mild conditions, the generated difluoromethyl heterocyclic anion was efficiently trapped with aromatic and heterocyclic aldehydes 7-14 and ketones 15-16. In this way the corresponding beta,beta-difluoro-alpha-heteroarylated alcohols 17-32 were obtained in moderate to good yields. The same methodology was successfully applied to the reduction of chlorodifluoromethylated ketones 4-6 and the generated alpha,alpha-difluoroacetyl anion was trapped with several aldehydes 7, 8, 10, 11, under mild conditions, to give the corresponding 2,2-difluoro-3-hydroxy ketone derivatives 33-38, in moderate yields. The SRN1 reactions of 2-(bromodifluoromethyl)benzoxazole (1) with the anions of heterocyclic thiols and phenolic compounds were also carried out. The products 39-54, which all have a CF2 group, were tested for activity against HIV, and several were found to be active, including 44 which was very active.
