The indium(III)-catalyzed cascade cycloisomerization reaction of 1,5-enynes with pendant aryl nucleophiles is reported. proceeds in under mild conditions, using InI3 (5 mol %) as a catalyst range furnished groups (phenyl and phenol) at alkene (E Z isomers) terminal internal alkynes. Using 1-bromo-1,5-enynes, one-pot sequential indium-catalyzed palladium-catalyzed cross-coupling triorganoindium ...

The classical studies of Dutton and Storey (1) have shown that liver microsomes catalyze the transfer of glucuronic acid from uridine diphosphate glucuronic acid to phenols. In an attempt to detect a reaction between uridine diphosphate glucuronic acid and uridine diphosphate N-acetylglucosamine, the effect of the latter on phenol glucuronidation was tested. It was expected that a reaction betw...

The first examples of reactions of Fischer carbene complexes with triynes are reported. The regioselectivity of the reaction of the two different alkyne functions in the symmetrical triyne depends on the nature of the substituent of the triyne. Bis-silyl-substituted triynes react at the central alkyne unit, whereas bis-aryl- and bis-alkyl-substituted triynes react at the end alkyne unit. The re...

The title compound, [Cu(2)(C(20)H(14)N(2)O(2))(2)]·2C(3)H(7)NO, consists of a centrosymmetric dimer composed of two copper(II) ions and two tetra-dentate salphen ligands {H(2)salphen is 2,2'-[o-phenyl-enebis(nitrilo-methyl-idyne)]diphenol}, and two dimethyl-formamide solvent mol-ecules. The Cu(II) atom is bonded to two N imino atoms and three phenolate O atoms of salphen. One deprotonated pheno...

Eugenol is an essential oil mainly found in the buds and leaves of clove (Syzygium aromaticum (L.) Merrill and Perry), which has been reported to have activity on inhibition of cell proliferation and apoptosis induction in human MCF-7 breast cancer cells. This biological activity is correlated to its activity as an estrogen receptor antagonist. In this article, we present the construction and v...

In the title compound, C13H11ClO2, the dihedral angle between the mean planes of the 2-chloro-phenyl and phenol rings is 87.4 (9)°. The methyl hy-droxy group lies nearly perpendicular to the plane of its attached benzene ring [O-C-C-C torsion angle = 84.3 (3)°]. The two hy-droxy groups lie on the same side of the mol-ecule and are in a slightly twisted gauche conformation [O-C-C-O torsion angle...

A new series of 2-(ortho & para substituted phenoxy)1-(3-(3-chloro-4-methoxyphenyl)-5-(substituted phenyl)-4,5dihydropyrazol-1-yl)ethanone were synthesized. Ortho and para substituted phenol was refluxed with ethylchloroacetate in dry acetone in presence of anhydrous potassium carbonate to yield ethyl (ortho & para substituted phenoxy) acetate (1). The substituted ester on reaction with hydrazi...
