In the title monomeric trimethyl-tin(IV) isothio-cyanate-4,4-dimethyl-pyridine adduct, [Sn(CH(3))(3)(NCS)(C(7)H(10)N(2))], the Sn(IV) atom shows a trans-C(3)SnN(2) trigonal bipyramidal coordination. The Sn(IV) atom lies out of the equatorial plane by 0.033 (4) Å in the direction of the donor N atom of the N-heterocycle. The crystal studied was a non-merohedral twin with a minor component of 48....

The title compound, [Co(C(30)H(23)O(2)P(2))(C(3)H(9)P)(2)], was synthesized by the addition of a Co(PMe(3))(4) solution to (PPh(2)O)(2)C(6)H(4). The Co(I) atom displays a trigonal-bipyramidal geometry with the two P atoms of the 'PCP' pincer ligand and the P atom of one of the trimethyl phosphine ligands forming the basal plane, whereas the metalated C atom and the P atom of the second phospine...

A series of 1,3-benzoxazole-4-carbonitriles was synthesized and evaluated for its antifungal activity, solubility, and metabolic stability. Among those compounds, 4-cyano-N,N,5-trimethyl-7-[(3S)-3-methyl-3-(methylamino)pyrrolidin-1-yl]-6-phenyl-1,3-benzoxazole-2-carboxamide (16b) exhibited potent in vitro activity against Candida species, higher water solubility, and improved metabolic stabilit...

Three quinolinone alkaloids, two acridone alkaloids and a flavones glycoside were isolated from the aerial parts of Glycosmis mauritiana. These compounds were characterized as 7, 8-Dimethoxy-2,2,6-trimethyl-pyrano quinolin-5-one, 4-Methoxy 1-methyl quinolin-2-one, 6-Hydroxy N-methyl 2,3-furo-quinolin-4-one, 1-Hydroxy-10-methyl acridone, 1Hydroxy-2, 3-dimethoxy-10-methylacridin-9-one and Luteoli...

A reaction between (E)-trimethyl(3,3,3-trifluoroprop-1-en-1-yl)silane (1) and arylaldehydes 2 was triggered by fluoride anions to afford aryl 3,3,3-trifluoropropyl ketones 3 in moderate to good yield. A mechanistic study of this reaction indicated that it occurred via an allyl alkoxide (4). A subsequent 1,3-proton shift of the benzylic proton of 4 forms 3. This reaction involves oxidative 3,3,3...

In the title compound, C17H15FO3S, the dihedral angle between the mean planes of the benzo-furan and 2-fluoro-phenyl rings is 87.61 (4) Å. In the crystal, mol-ecules are linked via pairs of C-H⋯π inter-actions into inversion-related dimers. These dimers are linked by C-H⋯O hydrogen bonds into supra-molecular chains running along the a-axis direction.
