Simple and efficient synthetic procedures for the selective preparation of 3-bromo/3-chloroindoles and 2,3-dibromo/2,3-dichloroindoles by using 1,3-dibromo-5,5-dimethylhydantoin (DBDMH) and 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) were developed. Using 1,4-dioxane as the solvent, a variety of indoles, treated with 0.55 equiv DBDMH/DCDMH, afford the corresponding 3-bromo/3-chloroindoles selectively in 82-99% yield. In 1,2-dichloroethane (DCE), a series of 2,3-dichloro/2,3-dibromoindoles were selectively obtained in 84-95% yield by treating with DBDMH/DCDMH. All the processes do not need extra catalysts, dry solvents, or harsh reaction conditions.

A validated LC-MS/MS-based candidate reference measurement procedure for the quantification of carbamazepine is presented in order to be used for standardization and harmonization of routine assays applied for therapeutic drug monitoring. Sample preparation was based on protein precipitation using acetonitrile followed by sample dilution. Since the previously listed certified reference material (CRM) SRM 1599 (anticonvulsant drug level assay standard) is no longer available, an ISO certified calibration material was used in this assay. As internal standards deuterated analyte congeners were applied. The method allows the measurement of carbamazepine, carbamazepine-10,11-epoxide and 10-hydroxy-10,11-dihydrocarbamazepine in the concentration range of 0.1 to 22.0 mug/ml with LODs and LOQs of < 0.1 mug/ml and 0.1 mug/ml, respectively. Comparative measurement of 105 native patient samples using the here presented method showed a good agreement between two independent laboratories with a mean bias of 0.6%.

The functionalization of C?H bonds with non-precious metal catalysts is an important research area for the development of efficient and sustainable processes. Herein, we describe the development of iron porphyrin catalyzed reactions of diazoacetonitrile with N-heterocycles yielding important precursors of tryptamines, along with experimental mechanistic studies and proof-of-concept studies of an enzymatic process with YfeX enzyme. By using readily available FeTPPCl, we achieved the highly efficient C?H functionalization of indole and indazole heterocycles. These transformations feature mild reaction conditions, excellent yields with broad functional group tolerance, can be conducted on gram scale, and thus provide a unique streamlined access to tryptamines.

A novel Friedel-Crafts reaction of indoles with vicinal tricarbonyl compounds generated in situ from 1,3-dicarbonyl compounds, which produces indole substituted tertiary alcohols in good to excellent yields and with good functional group tolerance, has been developed. The mechanistic pathway for this process involves the initial disproportionation of TEMPO, alpha-oxyamination of the 1,3-dicarbonyl compound followed by N-O bond cleavage to form the tricarbonyl intermediate. Addition of indole to this intermediate then generates the tertiary alcohol product. This method can also be used for the synthesis of pyrrole-containing tertiary alcohols. Further efforts aimed at elucidating the mechanism of the reaction and boardening the substrate scope of this process are ongoing.

The chemiluminescence (CL) intensities of various indole derivatives substituted with a glyoxylyl group at the 3-position and a hydroxyl group at the 5-position of the indole ring were compared upon the addition of H2O2 in alkaline media. The CL intensities of 3-indoleglyoxylyl chloride, 3-indoleglyoxylic acid, 5-hydroxyindole and 5-benzyloxyindole in CH3CN were 5.9-, 48-, 5.9- and 3.3-fold stronger than that of 3-methylindole. A lasting CL of 3-indoleglyoxylyl chloride was found. Under appropriate conditions, the CL emission reached a maximum within 10 min after the addition of H2O2 in the presence of NaOH, and the intensity was retained for 25 min. One of the final products via the CL reaction of 3-indoleglyoxylyl chloride was indole-3-carboxylic acid. 3-Indoleglyoxylyl chloride emitted light by decompositions via both dioxetane and dioxetanedione. An enhancement effect of beta-cyclodextrin and bovine serum albumin on the CL of 3-indoleglyoxylyl chloride was also found.

Sulfonylureas stimulate insulin secretion independent of the blood glucose concentration and therefore cause hypoglycemia in type 2 diabetic patients. Over the last years, a number of aryl-imidazoline derivatives have been identified that stimulate insulin secretion in a glucose-dependent manner. In the present study, we have developed three series of substituted N-(thieno[2,3-b]pyridin-3-yl)-guanidine (2a-l), N-(1H-pyrrolo[2,3-b]pyridin-3-yl)-guanidine (3a-l), and N-(1H-indol-3-yl)-guanidine (4a-l) as new class of antidiabetic agents. In vitro glucose-dependent insulinotropic activity of test compounds 2a-l, 3a-l, and 4a-l was evaluated using RIN5F (Rat Insulinoma cell) based assay. All the test compounds showed concentration-dependent insulin secretion, only in presence of glucose load (16.7 mmol). Some of the test compounds (2c, 3c, and 4c) from each series were found to be equipotent to BL 11282 (standard aryl-imidazoline), which indicated that the guanidine group acts as a bioisostere of imidazoline ring system.
