A (pyridyl)phosphine-ligated ruthenium(II) catalyst is reported for the chemoselective benzylic N-alkylation of amines, via a hydrogen-borrowing mechanism. The catalyst operates under mild conditions, neat, and without a base or other additive. These conditions offer remarkable functional group compatibility for applications in organic synthesis, including reactions involving phenols and anilines, which are very difficult to achieve. Mechanistic studies suggest that, unlike other catalysts for this reaction, the redox steps are fast and reversible while imine formation is slow. We perceive that this is the origin of the selectivity realized with these reaction conditions.

New verapamil analogues were synthesized and their inhibitory activities against Mycobacterium tuberculosis H37Rv determined in vitro alone and in combination with rifampicin (RIF). Some analogues showed comparable activity to verapamil and exhibited better synergies with RIF. Molecular docking studies of the binding sites of Rv1258c, a M. tuberculosis efflux protein previously implicated in intrinsic resistance to RIF, suggested a potential rationale for the superior synergistic interactions observed with some analogues.

, p. 157 - 177 (2007/10/02)
The apogalanthamine analogues, 5,6,7,8-tetrahydrodibenzazocine (2) and its N-methyl and N-acetyl derivatives (1 and 3), and the methoxy derivatives (4, 5 and 9) of (1) were obtained in good yields by cyclization of the corresponding halogeno-N-benzyl-β-phenethylamines (10a, 11a-d, 12a,b and 13a-c) using stoichiometric amounts of zerovalent nickel generated in situ and potassium iodide.

Synthesis, Positive and Negative Ion Mass Spectra and Microbial Activity of N-Benzyltetrahydroisoquinolines
Pant, Pushpa,Madhusudanan, K. P.,Bhakuni, D. S.
, p. 630 - 633 (2007/10/02)
Substituted N-benzyltetrahydroisoquinolines (5-11) have been synthesised and their positive and negative ion mass spectra studied.The M+. of these compounds are fairly stable and abundant RDA fragment ions (often corresponding to the base peaks) are observed in their positive ion EI spectra.However, under negative ion conditions these molecules fragment in a similar way as that of 1-benzyltetrahydroisoquinolines.The base (5-11) hydrochlorides when tested against a number of fungi and bacteria do not exhibit any promising activity.
