The present invention comprises TGR5 agonists of structural formula I, wherein X, R1, R2, and R5 are defined herein, as well as N-oxides of them and pharmaceutically acceptable salts thereof. The invention further comprises composition comprising the compounds, N-oxides, and/or pharmaceutically acceptable salts thereof. The invention also comprises use of the compounds and compositions for treating diseases in which TGR5 is a mediator or is implicated. The invention also comprises use of the compounds in and for the manufacture of medicaments, particularly for treating diseases in which TGR5 is a mediator or is implicated.
Abstract Benzal chlorides and benzal bromides were conveniently synthesized by reaction of aryl aldehydes with a Vilsmeier type reagent formed in situ by reduction of CC14 or CBr4 in dimethylformamide (DMF) as solvent.

Abstract A one-pot and oxidative method is described for the first time for the conversion of benzylic trimethylsilyl (TMS) and tetrahydropyranyl (THP) ethers to gem-dichlorides using trichloroisocyanuric acid (TCCA) and triphenylphosphine (PPh3) in neutral media. Various theses substrates containing electron withdrawing or donating groups can be efficiently converted to their corresponding gem-dichlorides
The substituent parameters for the series of mono-, di- and trisubstituted Me groups, CH2X, CHX2, and CX3 where X is F, Cl, Br, OMe, SCF3 and CN, have been determined from F19 NMR measurements on the corresponding meta- and para-fluorotoluenes. An additive linear effect of substitution is found only for the cyano substituent. A saturation effect noted for the groups where X is F, Cl, Br and SCF3 (particularly

alcohols to their corresponding gem-dichlorides is reported for the first time using chlorodiphenylphosphine (ClPPh2) and 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) in dichloromethane under neutral conditions and at room temperature. The present method can be efficiently used for preparation of gem-dichlorides even in the presence of some other functional groups with excellent chemoselectivity.
