Paragraph 0098; 0099, (2017/07/20)
The invention belongs to the field of pharmaceutical chemistry, and in particular relates to an imidazole heterocyclic diphosphonic acid compound as well as a preparation method and application thereof. The imidazole heterocyclic diphosphonic acid compound has a larger non-toxic concentration range for an osteoclast precursor, and can significantly inhibit the formation of osteoclasts at the same time; the imidazole heterocyclic diphosphonic acid compound can damage actin ring to the utmost extent, thus having an obvious inhibiting effect on the osteoclasts and further being used as an osteoclast inhibitor; the imidazole heterocyclic diphosphonic acid compound solves the problems that diphosphonate in the prior art is low in inhibiting effect on the osteoclasts, high in toxicity and large in side effects.

The interaction of salts of imidazole, 1,2,4-triazole, benzimidazole, and 2-benzylbenzimidazole with γ-butyrolactone has been studied. Ab initio quantum-chemical calculations showed a preference for N-alkylation on interaction of azolates with γ-butyrolac
Intramolecular inverse-electron-demand Diels-Alder reactions of imidazoles with 1,2,4-triazines: A new route to 1,2,3,4-tetrahydro-1,5-naphthyridines and related heterocycles

, p. 7171 - 7182 (2007/10/03)
The intramolecular inverse-electron-demand Diels-Alder reaction between imidazoles and 1,2,4-triazines linked by a trimethylene tether from the imidazole N1 position to the triazine C3 proceed in excellent yields to produce 1,2,3,4-tetrahydro-1,5-naphthyridines. The reaction proceeds by a cycloaddition with subsequent loss of nitrogen, followed by a presumed stepwise loss of a nitrile. The analogous intramolecular cycloadditions employing a tetramethylene tether also proceeded to give 2,3,4,5-tetrahydro-1H-pyrido[3,2-b]azepines in acceptable yields. The reaction to produce the tetrahydro-1,5-naphthyridines can also be promoted with microwave irradiation.

Imidazole and 2-phenylimidazole undergo intramolecular cycloadditions with 1,2,4-triazines tethered between an imidazole nitrogen and the triazinyl C3 position with a trimethylene chain to produce tetrahydro-1,5-naphthyridines following loss of N2/s
