The development of X-ray free-electron lasers (XFELs) has opened the possibility to investigate the ultrafast dynamics of biomacromolecules using X-ray diffraction. Whereas an increasing number of structures solved by means of serial femtosecond crystallog ...
The crystal structure of the Form A polymorph of N-cyclopropyl-3-fluoro-4-methyl-5-[3-[[1-[2-[2-(methylamino) ethoxy] phenyl] cyclopropyl] amino]-2-oxo-pyrazin-1-yl] benzamide (i.e., AZD7624), determined using single-crystal X-ray diffraction (scXRD) at 10 ...
Three new complexes, [(CoL2)-L-II(bzln)(2)] (1), [(NiL2)-L-II(DMF)(2)] (2), and [(ZnL2)-L-II] (3), with the bidentate (NO) Schiff base HL=2-((E)-(benzylimino)methyl)-4-nitrophenol have been synthesized and characterized. [(CoL2)-L-II(bzln)(2)] (1) was init ...
Enantioselective total syntheses of title natural products from a common cyclohexenone derivative (S)-18 were reported. Ozonolysis of (S)-18 afforded a stable diketo ester (R)-17 that was subsequently converted to two skeletally different natural products, ...
Two carboxamide ligands, H(2)bqbenzo {3,4-bis(2-quinolinecarboxamido)benzophenone} and H(2)bqb {N,N-bis[(2-quinolinecarboxamide)-1,2-benzene]}, have been prepared using tetrabutylammonium bromide as an environmentally benign reaction medium. Two new Pd(II) ...
The synthesis of a series of neutral arene-ruthenium (II) complexes (arene = p-cymene, hexamethylbenzene, and benzene) [(arene)Ru(HDB) Cl] derived from the reaction of the appropriate arene-ruthenium(II) dimers and ortho-hydroxydibenzoylmethane (HDBH), a p ...
Regioselective electrophilic substitution reactions of the iridabenzofurans [Ir(C7H5O{OMe-7})(CO)(PPh3)(2)]-[OTf] (1) and IrCl(C7H5O{OMe-7})(PPh3)(2) (2) provide a convenient route to mononitro-, dinitro-, and mixed nitro-/halo- substituted derivatives. Tr ...
Complexes with general formula p,t-[Ru(CO)(PR3)(tren)]X-2 [R=Ph (1) or p-tol (2); tren=tris(2-aminoethyl)amine; X=Cl- or PF6-] were prepared from [RuCl2(CO)(dmf)(PR3)] by direct reaction with tren. The complexes were fully characterized by NMR (H-1, P-31{H ...
Some triphenyltin(IV) adducts with a family of diphosphoryl ligands, RR'P(O)-X-P(O)RR' (R = OPh, Ph, R' = R, An (aniline)) and X = 1,4-OC6H4O, 1,4-OC6H4NH, 1,4-NHC6H4NH 1,4-(NHCH2)(2)C6H4, 1,3-(NHCH2)(2)C6H4 and piperazine have been synthesized and charact ...
A series of novel symmetrically and unsymmetrically coordinated platinum(IV) complexes with monodentate carboxylato ligands was synthesized. The compounds exhibit a general coordination sphere of [Pt(en)(OCOR)(2)(OCOR')(OCOR '')1, where the carboxylato lig ...
