Exempel på hur man kan använda AMIDINE i en mening

• With ammonia or an amine to form an amidine (di-nitriles may form imidines, for instance succinimidine from succinonitrile).
• For example, heating demoxepam with N-cyclopropylmethylamine leads to amidine formation, the minor tranquilizer cyprazepam.
• In particular they contain indole alkaloids derived from Beta-carboline such as harmine, tetrahydroharmine, harmaline, manacin, manacein, and dimethyltryptamine and amidine derivatives such as pyrrole 3-carboxamidine.
• The reaction may well involve conjugate addition of the amidine nitrogen to the malononitrile followed by loss of ethoxide (3); addition of the remaining amidine nitrogen to one of the nitriles will then lead to the pyrimidine (4).
• The corrin chromophore system is thus non-cyclic and expands over three meso positions only, incorporating three vinylogous amidine units.
• The amidine group on NAPAP forms a bidentate salt bridge with Asp deep in the S1 pocket, the piperidine group takes the role of proline residue and binds in the S2 pocket, and the naphthyl rings of the molecule forms a hydrophobic interaction with Trp in the S4 pocket.
• The condensation of bromazepam (1) with methylamine and titanium tetrachloride gives the amidine (2).
• The structure was confirmed in the 1980s and 1990s to be a cyclic iminopeptide based on NMR studies, with a linear side chain connected to the macrocycle via an amidine linkage.
• In organic chemistry, the Graham reaction is an oxidation reaction that converts an amidine into a diazirine using a hypohalite reagent.
• Linneman also discovered that sulfur dicyanide reacts with ammonia à la Pinner to give an amidine without displacing the S–C linkage, although dimethylamine induces decomposition to dimethylcyanamide and dimethylammonium thiocyanate.
