The crystal structure of the title compound, C(8)H(6)FN(3)O, is stabilized by C-H⋯O hydrogen bonds, which link the mol-ecules into chains running parallel to the a axis.

An azido-avermectin analog [4'' alpha-(4-azidosalicylamido-epsilon-caproylamido-beta-alan ylamido)-4''-deoxyavermectin B1a; azido-AVM] was synthesized and used to photoaffinity label avermectin binding sites present in the membranes of Caenorhabditis elegans and Drosophila melanogaster. Azido-AVM was biologically active and behaved like a competitive inhibitor of [3H]ivermectin binding to C. el...

The Povarov reaction of p-anisidine, cinnamaldehyde and methacrolein dimethylhydrazone afforded a 1,2,3,4-tetrahydroquinoline derivative bearing 2-styryl, 4-methyl 4-dimethylhydrazono substituents in fully diastereoselective fashion. This is the first example combination type I aza-vinylogous II vinylogous same process.

In the title compound, [Co(C(12)H(12)N(2))(2)(N(3))(2)]·H(2)O, the Co(II) ion is situated on a crystallographic twofold axis and adopts a distorted octa-hedral geometry with the two dmbpy (dmbpy = 5,5'-dimethyl-2,2'-bipyrid-yl) and the two azido ligands in a cis arrangement. The solvent water mol-ecule and one methyl group of the dmbpy ligand are disordered over two sets of sites in a 1:1 ratio...
