A convenient one-pot method for the synthesis of 4-arylquinolin-2(1H)-ones and 4-arylcoumarins has been described. The successive Heck reaction on substituted 2-iodoaniline and 2-iodophenol catalyzed by a Pd/nickel ferrite catalyst followed by in situ cyclization was the key step. The scope of this methodology was extended to the synthesis of bioactive 3-alkenyl derivatives of 4-arylquinolin-2(1H)-ones.

Palladium can do it! A novel palladium-catalyzed reaction between the bulky alpha-carbon centers of two ketones has led to the construction of 2,3-diaryl-1,4-diketones by employing alpha-chloroketones as electrophiles and zinc ketone enolates as nucleophiles (see scheme). This reaction allows the synthesis of bulky 1,4-diketones and is complementary with classic nucleophilic substitution reactions. Copyright

A tandem relay catalytic protocol using both Pd and isothiourea catalysis has been developed for the enantioselective synthesis of alpha-amino acid derivatives containing two stereogenic centers from readily accessible N,N-disubstituted glycine aryl esters and allylic phosphates. The optimized process uses a bench-stable succinimide-based Pd precatalyst (FurCat) to promote Pd-catalyzed allylic ammonium salt generation from the allylic phosphate and the glycine aryl ester. Subsequent in situ enantioselective [2,3]-sigmatropic rearrangement catalyzed by the isothiourea benzotetramisole forms syn-alpha-amino acid derivatives with high diastereo- and enantioselectivity. This methodology is most effective using 4-nitrophenylglycine esters and tolerates a variety of substituted cinnamic and styrenyl allylic ethyl phosphates. The use of challenging unsymmetrical N-allyl-N-methylglycine esters is also tolerated under the catalytic relay conditions without compromising stereoselectivity.

Direct and selective mono-N-pyridylation of trans-(R,R)-cyclohexane-1,2- diamine is described here. Facile preparation of a novel chiral 2-aminoDMAP core catalaphore via Cu catalysis has led to the development of various sulfonamide/2-aminoDMAPs as bifunctional acid/base organocatalysts (most in two steps overall), which have been shown to very effectively promote asymmetric conjugate addition of acetylacetone to trans-beta-nitroolefins with good to excellent yields (87-93%) and enantioselectivites (up to 99%).

The novel P,N-ligand 2-[2-(diphenylphosphino)phenyl]-4,5-dihydro-4-methyl-4-phenyloxazole (2a) has been synthesized. The corresponding [PdII(eta3-diphenylallyl) (2a)]PF6 (3a) and [PdII(eta3-1,3-dimethylallyl) (2a)]PF6 (4a) complexes have been studied by X-ray analysis and NMR spectroscopy. 3a exists as exo-syn-syn isomer in the solid state. In solution, the same isomer predominates. The X-ray structure of 4a reveals that the oxazoline ligand is coordinated in a pseudo-enantiomeric conformation compared with 3a. A syn-anti arrangement of the allyl substituents is favored in the solid state. NMR spectroscopical investigations suggest a formation of six isomers in solution due to endo-exo orientation of the allyl moiety and syn-anti isomerization of the methyl substituents. NMR data of [Pd0(eta2-dimethylfumarate)(phosphinooxazoline)] complexes give evidence that two isomers exist in solution. The isomeric ratio is strongly dependent on the steric bulk of the oxazoline substituents. The solid state structures of [Pd0(eta2-dmfu) (2c)] and [Pd0(eta2-dmfu) (1a)] confirmed the structures of the main isomer found in solution. The asymmetric allylic substitution reaction of 1,3-diphenylallyl acetate with dimethyl malonate catalyzed by 3a proceeds with a selectivity of 97% ee. The ee induced by 2a in catalytic allylic substitution of 1-methylbutenyl acetate is moderate (18%). A comparison of the intermediate 4a and 5a as model of the actual olefinic intermediate suggests that the poor enantioselectivity achieved with ligand 2a is due to the preferred formation of anti-isomers of the allylic intermediate 4a and the conformational instability of the complex.

Background: Since its discovery on the 1930 decade, phthalocyanines have occupied a prominent place in the textile and dye industries due to their thermal stability, low solubility and reactivity. However, over the last three decades, many different applications have been found for phthalocyanine derivatives including medicine, materials science, catalysis and energy fields. In this review, we discuss about the phthalocyanine chemistry, and the principal synthetic precursors as well. Strategies developed for obtaining soluble and non-aggregated phthalocyanine dyes are also covered, with insights on the reaction mechanisms. The main synthetic methods for the synthesis of symmetric and non-symmetric systems are presented and discussed. Objective: This review aims to present an overview on phthalocyanine chemistry and their principal synthetic precursors, covering strategies developed for obtaining soluble and non-aggregated phthalocyanine dyes with insights on the reaction mechanisms. Also, the main synthetic methods are presented, and different approaches to symmetric and non-symmetric phthalocyanine are discussed. Conclusion: Phthalocyanines are compounds with significant applications and growing interest in science. Their physical and chemical properties have been more and more elucidated. The major challenge is to make the synthetic protocols more suitable and cheaper, in order to allow studies and application on large scales.
