In the title compound, C(26)H(23)NO, C-H⋯O hydrogen bonds generate a ribbon structure along the a axis. These ribbons further assemble into a one-dimensional sheet parallel to the ac plane via C-H⋯π inter-actions. The piperidin-4-one ring adopts a sofa conformation with the 1-benzyl group in the equatorial position, and the 3- and 5-phenyl substituents stretched out on either side. The benzyl-i...

positively on the number of methoxyl groups on the benzyl moiety, and the homopiperazine analogs seem to be equipotent to the corresponding piperazines. From the standpoints of potency and ease of synthesis, 8k was selected for further study. Further analogs, which have various substituents in place of the benzyl moiety of 8k, were prepared and tested for cerebral vasodilating activity. These a...

Trisubstituted 5-stibano-1H-1,2,3-triazoles were synthesized in moderate to excellent yields by the Cu-catalyzed [3 + 2] cycloaddition of a ethynylstibane with organic azides in the presence of CuBr (5 mol %) under aerobic conditions. The reaction of 5-stibanotriazole with HCl, I2, and NOBF4 afforded 1-benzyl-4-phenyltriazole, 1-benzyl-5-iodo-4-phenyltriazole, and a pentavalent organoantimony c...

derivatives of thiazolidinone ring systems are known to act as anti-hiv infections , analgesic, anti-bacterial, anti-convulsant, anti parasitic, potential anti-inflammatory and herbicidal agents. due biological activities of thiazolidinones ring, several methods for their synthesis have been illustrated in literature. imidazolidine-2-thiones were synthesized by the oxidative cyclization of 1-be...

In the title compound, C(7)H(9)NO, a derivative of benzyl alcohol, the endocyclic C-C-C angles are in the range 119.50 (12)-121.04 (12)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen-bond inter-actions, forming an extended two-dimensional framework parallel to ab. O-H⋯N inter-actions are also observed.

In the title compound, C(11)H(11)N(3)O(2), prepared by the [3+2] cycloaddition reaction of benzyl azide with methyl propiolate, the dihedral angle between the ring planes is 67.87 (11)°.

Alkyldifluorophosphites, ROPF2 (R = ^-substituted benzyl group, neopentyl, 1-adamantyl) have been obtained by a new method, involving reaction of the appropriate alkyl trimethylsilylether, ROSiMe3 with chlorodifluorophosphine, PF2C1. Reactions of these difluorophosphites with platinum(II) complexes of the type [LaPtCla] (L = PEt3, PPI13) led to products such as irans-[L2PtCl(POF2)] and {[p-XC6H...

The enantiomers of XYLNAc (2-N-acetylamino-1,2,4-trideoxy-1,4-iminoxylitol) are prepared from the enantiomers of glucuronolactone; the synthesis of the enantiomers of LYXNAc (2-N-acetylamino-1,2,4-trideoxy-1,4-iminolyxitol) from an L-arabinono-δ-lactone and a D-ribono-δ-lactone is reported. A comparison is made of the inhibition of β-N-acetylhexosaminidases (HexNAcases) and α-N-acetylgalactosam...
