Palladium(II)-catalyzed synthesis of functionalized indenones via oxidation and cyclization of 2-(2-arylethynylphenyl)acetonitriles.

Xuxing Chen et al.

Organic & biomolecular chemistry, 11(16), 2582-2585 (2013-03-19)

A one-pot two-step synthesis of versatile indenones has been developed. This palladium(II)-catalyzed transformation involves generation and condensation of ortho-functionalized 1,2-benzils from 2-(2-arylethynylphenyl)acetonitriles using Ph2SO as the oxidant. The resulting 3-cyanoindenones can be converted to various valuable molecules.

Pd(0)-catalyzed alkene oxy- and aminoalkynylation with aliphatic bromoacetylenes.

Stefano Nicolai et al.

The Journal of organic chemistry, 78(8), 3783-3801 (2013-03-21)

Tetrahydrofurans and pyrrolidines are among the most important heterocycles found in bioactive compounds. Cyclization-functionalization domino reactions of alcohols or amines onto olefins constitute one of the most efficient methods to access them. In this context, oxy- and aminoalkynylation are especially

A novel convenient approach towards pyrrolo[1,2-b]pyridazines through a domino coupling-isomerization-condensation reaction.

Meng Wang et al.

Organic & biomolecular chemistry, 11(16), 2574-2577 (2013-03-15)

A novel Pd/Cu catalyzed domino reaction for the synthesis of functionalized pyrrolo[1,2-b]pyridazines from readily accessible (hetero)aryl propargyl alcohols and 1-amino-2-bromopyrroles was developed. This cascade process involves a Sonogashira cross-coupling reaction, an isomerization and an intramolecular condensation.

Stereoretentive Pd-catalysed Stille cross-coupling reactions of secondary alkyl azastannatranes and aryl halides.

Ling Li et al.

Nature chemistry, 5(7), 607-612 (2013-06-22)

The development of transition metal-catalysed cross-coupling reactions has greatly influenced the manner in which the synthesis of complex organic molecules is approached. A wide variety of methods are now available for the formation of C(sp(2))-C(sp(2)) bonds, and more recent work

Cytotoxic effects of palladium (II) and platinum (II) complexes with O,O'-dialkyl esters of (S,S)-ethylenediamine-N,N'-di-2-(4-methyl) pentanoic acid on human colon cancer cell lines.

V Volarevic et al.

Journal of B.U.ON. : official journal of the Balkan Union of Oncology, 18(1), 131-137 (2013-04-25)

As novel therapeutic agents relevant to colon cancer therapy are explored continuously, we tested 4 R2edda-type ligand precursors O,O'-dialkyl esters of (S,S)-ethylenediamine-N,N'-di-2-(4-methyl)pentanoic acid (L1.2HCl-L4.2HCl) and corresponding palladium(II) and platinum(II) complexes against the human colon cancer cell lines CaCo-2, SW480 and
