A series of novel tetrahydropyridine derivatives were prepared and evaluated using cell-based measurements. Systematic optimization of general structure G-1 led to the identification of compound 35 (EC50 = 4.9 nM) and 37 (EC50 = 8.8 nM) with high GPR119 agonism activity and moderate clog P. Through single and long-term pharmacodynamic experiments, we found that compound 35 showed a hypoglycemic effect and may have an effect on improving basal metabolic rate in DIO mice. Both in vitro and in vivo tests indicated that compound 35 was a potential potent GPR119 agonist in allusion to T2DM treatment.

scheme or table, p. 556 - 560 (2010/08/20)
Diazotization of 1-(aminophenyl)-1H-tetrazoles and subsequent treatment of the diazonium salts with sodium azide gave 1-(azidophenyl)-1H-tetrazoles which were brought into cyclization with ethyl acetoacetate and cyanoacetanilide to obtain 1,2,3-triazole derivatives. Under these conditions, the tetrazole ring may undergo cleavage with formation of cyanamide group.

Optically active antifungal azoles. XI. An alternative synthetic route for 1-[(1R,2R)-2-(2,4-difluorophenyl)-2-hydroxy-1-methyl-3-(1H-1,2,4-triazol-1-yl )propyl]-3-[4-(1H-1-tetrazolyl)phenyl]-2-imidazolidinone (TAK-456) and its analog

New routes for the synthesis of the optically active antifungal triazoles 1-[(1R,2R)-2-(2,4-difluorophenyl)-2-Hydroxy-1-Methyl-3-(1H-1,2,4-triazol-1-Yl )propyl]-3-[4-(1H-1-tetrazolyl)phenyl]-2-imidazolidinone (1b) and the 3-[4-(1H-1,2,3-triazol-1-Yl)phenyl]-2-imidazolidinone analog (1a) that possess an imidazolidine nucleus were established. The key synthetic intermediates, (2R,3R)-3-(2,2-diethoxyethyl)amino-2-(2,4-difluorophenyl)-1-(1H-1,2,4-triazol -1-Yl)-2-butanol (8) and (2R,3R)-2-(2,4-difluorophenyl)-3-(2-hydroxyethyl)amino-1-(1H-1,2,4-triazol-1- yl)-2-butanol (14), were prepared by the ring-Opening reaction of the oxirane (2) with the corresponding 2-Substituted ethylamines. The acetal (8) was converted to the imidazolidinones (1a, b) by condensation with the carbamates (10a, b) followed by treatment with hydrochloric acid and subsequent catalytic hydrogenation. The candidate selected for the clinical trials, 1b (TAK-456), was alternatively prepared from the hydroxyethylamino intermediate (14) via two reaction steps: condensation with the carbamate (10b) to the urea (15) and subsequent cyclization to the imidazolidinones. This newly developed synthetic route could be applied to a large scale preparation of 1b.

A kinetic investigation of the thermal rearrangement of allyloxytetrazoles to N-allyltetrazolones
Cristiano, M. Lurdes S.,Johnstone, Robert A. W.
, p. 489 - 494 (2007/10/03)
The mechanism of the thermal rearrangement of 1-aryl-5-allyloxytetrazoles 1 to give 1-aryl-4-allyltetrazolones 2 in very high yield has been investigated through kinetic studies in one polar and one less polar solvent. The results suggest mainly a concerted [3,3] sigmatropic process, in which a partially positively charged allyl group migrates from oxygen to nitrogen, similar to the polar transition state found in the Claisen rearrangement.

Heterocyclization of m- and p-phenylenediamines with orthoformic ester and sodium azide has given phenylenebis-1H-tetrazoles.Under these conditions, o-phenylenediamine gives benzimidazole. o-, m-, and p-Phenylenebis-1H-tetrazoles were also obtained from the nitroanilines via the intermediate nitro- and aminophenyltetrazoles.The reactions of the bistetrazoles examined were basic hydrolysis, aminomethylation, and complex formation with copper salts.
