Nickel boride catalyst prepared in situ from NiCl2 and sodium borohydride allowed, in the presence of an aqueous solution of TEMPO-oxidized nanocellulose (0.01 wt%), the reduction of a wide range of nitroarenes and aliphatic nitro compounds. Here we describe how the modified nanocellulose has a stabilizing effect on the catalyst that enables low loading of the nickel salt pre-catalyst. Ni-B prepared in situ from a methanolic solution was also used to develop a greener and facile reduction of organic azides, offering a substantially lowered catalyst loading with respect to reported methods in the literature. Both aromatic and aliphatic azides were reduced, and the protocol is compatible with a one-pot Boc-protection of the obtained amine yielding the corresponding carbamates. Finally, bacterial crystalline nanocellulose was chosen as a support for the Ni-B catalyst to allow an easy recovery step of the catalyst and its recyclability for new reduction cycles.

Iron-Catalyzed Nitrene Transfer Reaction of 4-Hydroxystilbenes with Aryl Azides: Synthesis of Imines via C=C Bond Cleavage

C=C bond breaking to access the C=N bond remains an underdeveloped area. A new protocol for C=C bond cleavage of alkenes under nonoxidative conditions to produce imines via an iron-catalyzed nitrene transfer reaction of 4-hydroxystilbenes with aryl azides is reported. The success of various sequential one-pot reactions reveals that the good compatibility of this method makes it very attractive for synthetic applications. On the basis of experimental observations, a plausible reaction mechanism is also proposed.

Non-urea functionality as the primary pharmacophore in soluble epoxide hydrolase inhibitors
Anandan, Sampath-Kumar,Do, Zung N.,Webb, Heather K.,Patel, Dinesh V.,Gless, Richard D.
body text, p. 1066 - 1070 (2009/09/04)
Inhibition of soluble epoxide hydrolase has been proposed as a promising new pharmaceutical target for diseases involving hypertension and vascular inflammation. The most potent sEH inhibitors reported to date contain a urea or amide moiety as the central or 'primary' pharmacophore. We evaluated replacing the urea pharmacophore with other functional groups such as thiourea, sulfonamide, sulfonylurea, aminomethylene amide, hydroxyamide, and ketoamide to identify novel and potent inhibitors. The hydroxyamide moiety was identified as a novel pharmacophore affording potency comparable to urea.
