Provided are a tetrahydroisoquinoline derivative, a preparation method therefor and an application thereof in medicine. In particular, provided are a tetrahydroisoquinoline derivative represented by general formula (I), a preparation method therefor and a pharmaceutically acceptable salt thereof as well as use thereof as a therapeutic agent, in particular as an angiotensin II type 2 receptor (AT
2
R) antagonist, wherein definitions of substituent groups in the general formula (I) are the same as definitions in the description.
Imidazole derivatives of the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3, independently, are hydrogen, halogen, trifluoromethyl, nitro, lower alkyl or lower alkylthio; one of R.sup.4 and R.sup.5 is hydrogen and the other is hydrogen, halogen, hydroxy or lower alkoxy; R.sup.6 is hydrogen or lower alkyl; R.sup.7 is hydrogen, hydroxy, lower alkyl or lower alkoxy; and either R.sup.8 is hydrogen, lower alkyl, lower alkenyl, aryl(lower alkyl) or acyl and R.sup.9 taken together with R is an additional bond, or R.sup.9 is lower alkyl, lower alkenyl or aryl(lower alkyl) and R.sup.8 taken together with R is an additional bond; provided that R.sup.4 or R.sup.5 is not hydroxy when R.sup.7 is lower alkoxy and/or R.sup.8 is acyl, and that R.sup.7 is not hydroxy when R.sup.4 or R.sup.5 is lower alkoxy and/or R.sup.8 is acyl, and their pharmaceutically acceptable acid addition salts are described, the compounds of formula I have valuable therapeutic properties and are especially useful as analgesics.

reaction, because noncommercial analogues usually entail challenging syntheses. In this work, di(2-picolyl)amines (DPAs) are explored as an alternative modular ligand class for the nickel-catalyzed aryl–alkyl cross-electrophile coupling. Novel DPA ligands were synthesized directly from inexpensive amine and pyridine building blocks in a single step. This facile synthetic route enabled the parallel synthesis
