Straightforward and Regioselective Access to Unsaturated alpha-Benzyl Butyrolactones

The efficient preparation of various substituted alpha-benzyl unsaturated butyrolactones is described. The palladium-mediated C?C bond formation that uses alpha-bromomethylbutenolide and boron derivatives as coupling partners accounts for the key step of this synthetic approach. Our strategy exclusively affords the endocyclic adduct and represents an alternative to Heck-type reactions. The synthesis and characterization of two nostoclide analogues has also been reported.

Palladium-catalyzed enantioselective Heck alkenylation of trisubstituted allylic alkenols: a redox-relay strategy to construct vicinal stereocenters

An enantioselective, redox-relay Heck alkenylation of trisubstituted allylic alkenol substrates has been developed. This process enables the construction of vicinal stereocenters in high diastereo- and enantioselectivity and allows the formation of enolizable alpha-carbonyl methyl-substituted stereocenters with no observed epimerization under the reported reaction conditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C51H42O3Pd2, you can also check out more blogs about52409-22-0

Structures and Fluorescent Properties of Cadmium(II) Complexes with 1D and 2D Structures Based on Tridentate Benzimidazole Ligands

The cadmium(II) complexes [CdL1(m-nba)2] (1), [CdL1(p-nba)2]¡¤C2H5OH (2), [CdL2(p-nba)2]¡¤CH3OH (3), and [CdL2(p-nbat)2] (4) containing the ligands L1 and L2 [L1 = 2,6-bis(benzimidazol-2-yl)pyridine, L2 = bis(2-benzimidazolylmethyl)amine] were synthesized and characterized (m-nba, p-nba, and p-nbat are the anions of p-nitrobenzoic acid, m-nitrobenzoic acid, and p-nitrobenzeneacetic acid, respectively). The complexes were investigated by X-ray single crystal diffraction, elemental analysis as well as IR and fluorescence spectroscopy. Compounds 1-3 contain a distorted pentagonal bipyramidal coordination sphere with CdII coordinated by two carboxylate ligands in bidentate-chelating mode, whereas complex 4 exhibits a distorted octahedral arrangement with one carboxylate ligand in bidentate-chelating and the other in monodentate coordination mode. 1 and 2 form a 1D chain interplayed by hydrogen bonding and strong pi-pi stacking interactions. 3 and 4 vary from 1D chain into 2D single-layer and double-layer networks because of more extensive hydrogen bonding interactions. The complexes show emission maxima in the blue region in the solid state and emission bands are red-shifted compared to those of the free ligands.

Diastereo- A nd Enantioselective Synthesis of Homoallylic Amines Bearing Quaternary Carbon Centers

A Cu-catalyzed method for the efficient enantio- A nd diastereoselective synthesis of chiral homoallylic amines bearing a quaternary carbon and an alkenylboron is disclosed. Transformations are promoted by a readily prepared (phosphoramidite)-Cu complex and involve bench-stable I,I-disubstituted allyldiborons and benzyl imines; products are obtained in up to 82% yield, >20:1 dr, and >99:1 er. Reactions proceed via stereodefined boron-stabilized allylic Cu species formed by an enantioselective transmetalation. Utility of the 1-amino-3-alkenylboronate products is highlighted by a variety of synthetic transformations.

Synthesis, Structure, and Catalysis of Palladium Complexes Bearing a Group 13 Metalloligand: Remarkable Effect of an Aluminum-Metalloligand in Hydrosilylation of CO2

Efficient synthesis and catalysis of a series of palladium complexes having a group 13 metalloligand (Al, Ga, In) are reported utilizing 6,6-bis(phosphino)terpyridine as a new scaffold for Pd-E bonds (E = Al, Ga, In). Systematic investigation revealed unique characteristics of the Al-metalloligand in both structure and reactivity, which exhibited the highest catalytic activity for hydrosilylation of CO2 ever reported (TOF = 19 300 h-1). This study demonstrated fine-tuning of catalyst activity by the precisely designed metalloligand is a promising approach for new catalyst development in synthetic organometallic chemistry.

Synthesis of a novel polycyclic ring scaffold with antimitotic properties via a selective domino Heck-Suzuki reaction

The synthesis of a previously undescribed sp3-rich 6-5-5-6 tetracyclic ring scaffold using a palladium catalysed domino Heck-Suzuki reaction is reported. This reaction is high-yielding, selective for the domino process over the direct Suzuki reaction and tolerant towards a variety of boronic acids. The novel scaffold can also be accessed via domino Heck-Stille and radical cyclisations. Compounds based around this scaffold were found to be effective antimitotic agents in a human cancer cell line. Detailed phenotypic profiling showed that the compounds affected the congression of chromosomes to give mitotic arrest and apoptotic cell death. Thus, a novel structural class of antimitotic agents that does not disrupt the tubulin network has been identified. This journal is

Insertion of Pt into C-H and C-S bonds of thiophene derivatives. The X-ray crystal structure of a thiaplatinacycle of 3,6-dimethylthieno [3,2-b]thiophene

Treatment of the zerovalent platinum complex [Pt(PEt3) 4] with 3,6-dimethylthieno[3,2-b]thiophene leads to a six-membered, approximately planar thiaplatinacycle, which has been characterised spectroscopically and by a single crystal X-ray determination. The reaction of [Pt(PEt3)4] with 2,2?-bithiophene and 1-methyl-2-(2-thienyl)pyrrole produced two types of products, thiaplatinacycles resulting from C-S insertion and platinum(II) hydrides arising from C-H insertion. These complexes were characterised spectroscopically.
