The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane(SMILESS: CC1(C2)OC(C3)(C)OC2(C)OC3(C)P1C4=CC=CC=C4,cas:97739-46-3) is researched.Recommanded Product: 175543-06-3. The article 《Advancing Base-Metal Catalysis: Development of a Screening Method for Nickel-Catalyzed Suzuki-Miyaura Reactions of Pharmaceutically Relevant Heterocycles》 in relation to this compound, is published in Organic Process Research & Development. Let’s take a look at the latest research on this compound (cas:97739-46-3).

Interest in replacing palladium catalysts with base metals resulted in the development of a 24-reaction screening platform for identifying nickel-catalyzed Suzuki-Miyaura reaction conditions. This method was designed to be directly applicable to process scale-up by employing homogeneous reaction conditions alongside stable and inexpensive nickel(II) precatalysts and has proven to be broadly suitable for complex heterocyclic substrates relevant to bioactive mols. These advances were enabled by the key discovery that a methanol additive greatly improves the reaction performance and enables the use of organic-soluble amine bases. The screening platform and scale-up workflow were applied to a representative cross-coupling using the antipsychotic perphenazine and enabled the rapid development of a gram-scale synthesis that highlighted the utility of this method and the advantages of nickel catalysis for metal remediation.

Keywords: medicinal chem drug discovery high throughput synthesis. Let’s learn more about this compound (cas:97739-46-3).

At the forefront of new synthetic endeavors, such as drug discovery or natural product synthesis, large quantities of material are rarely available and timelines are tight. A miniaturized automation platform enabling high-throughput experimentation for synthetic route scouting to identify conditions for preparative reaction scale-up would be a transformative advance. Because automated, miniaturized chem. is difficult to carry out in the presence of solids or volatile organic solvents, most of the synthetic toolkit cannot be readily miniaturized. Using palladium-catalyzed cross-coupling reactions as a test case, we developed automation-friendly reactions to run in DMSO at room temperature This advance enabled us to couple the robotics used in biotechnol. with emerging mass spectrometry-based high-throughput anal. techniques. More than 1500 chem. experiments were carried out in less than a day, using as little as 0.02 mg of material per reaction. The synthesis of the target compounds was achieved using as starting materials N-(1,1-dimethylethyl)-4′-[(6-iodo-4-oxo-2-propyl-3(4H)-quinazolinyl)methyl][1,1′-biphenyl]-2-sulfonamide, (5R)-3-(3-fluoro-4-iodophenyl)-5-(1H-1,2,3-triazol-1-ylmethyl)-2-oxazolidinone, 7-[(3-bromo-4-methoxyphenyl)methyl]-1-ethyl-3,7-dihydro-8-[[(1R,2R)-2-hydroxycyclopentyl]amino]-3-(2-hydroxyethyl)-1H-purine-2,6-dione.

Compound: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane, is researched, Molecular C16H21O3P, CAS is 97739-46-3, about Titanium Complexes of Sterically Demanding Cage-Phosphinimide Ligands. Author is Carraz, Charles-Antoine; Stephan, Douglas W..

The known ligand PPh(C6H4O3Me4) (1) and its analog PCy(C6H4O3Me4) (2) have been prepared In the latter synthesis the diphosphine species (PCy)2(C6H2O3Me4) (3) was also isolated as a minor product. Reaction of the cage phosphines 1 and 2 with Me3SiN3 effected oxidation to the corresponding (trimethylsilyl)phosphinimines Me3SiNPR(C6H4O3Me4) (R = Ph (4), Cy (5)). Subsequent reactions afforded the titanium complexes CpTiCl2(NPR(C6H4O3Me4)) (R = Ph (6), Cy (7)) and CpTiMe2(NPR(C6H4O3Me4)) (R = Ph (8), Cy (9)). Preliminary screening for catalytic activity in ethylene polymerization employing either methylalumoxane (MAO) or [Ph3C][B(C6F5)4] as the activator showed minimal catalytic activity. These observations were probed via reactions of these complexes with AlMe3, MAO, or [Ph3C][B(C6F5)4]. Reaction of 8 with AlMe3 gave several products, one of which was fully characterized as the cage-rupture product CpTiMe2(NPCy(C6H4O3Me5)(μ-AlMe2)(AlMe3)) (10). A similar product is inferred by the spectroscopic monitoring of the reaction of 8 with MAO. In contrast, reaction of 2 with AlMe3 resulted only in the formation of the adduct Me3AlPCy(C6H4O3Me4) (11). Structural data are reported for 2, 3, 8, 10, and 11.

Oxaphosphaadamantane ligands bearing a variety of aryl and alkyl substituents were synthesized as catalyst promoters in the Pd-catalyzed telomerization of butadiene with methanol. At high methanol concentrations (14 M), ligands with electron-donating substituents on the aryl ring generate catalysts that lead to some of the highest conversions of butadiene and selectivities for 1-methoxy-2,7-octadiene under the conditions tested. Specifically, the ligand 1,3,5,7-tetramethyl-6-(2-methoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane, when combined with a Pd(II) precursor, forms a catalyst that converts 96% of butadiene with 94% selectivity for 1-methoxy-2,7-octadiene at 70 °C and is highly active for telomerization at a low reaction temperature (40 °C).

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane( cas:97739-46-3 ) is researched.Category: tetrahydropyran.Clarke, Matthew L.; Roff, Geoffrey J. published the article 《Highly regioselective rhodium-catalyzed hydroformylation of unsaturated esters: The first practical method for quaternary selective carbonylation》 about this compound( cas:97739-46-3 ) in Chemistry – A European Journal. Keywords: regioselective hydroformylation unsaturated carboxylic acid ester rhodium phosphine catalyst; alkyne conversion amino acid ester. Let’s learn more about this compound (cas:97739-46-3).

Highly regioselective hydroformylation of unsaturated esters can be achieved when a highly reactive, ligand-modified, rhodium catalyst is employed near ambient temperatures (15-50°C) and pressures over 30 bar. The use of 1,3,5,7-tetramethyl-2,4,8-trioxa-6-phosphaadamantane shows distinct advantages over other commonly applied phosphanes in terms of reaction rate, and regio- and chemoselectivity. Hydroformylation of a range 1,1-di-, and 1,1,2-trisubstituted unsaturated esters yields quaternary aldehydes that are forbidden products according to Keulemans Rule. The aldehydes can be reductively aminated with mol. hydrogen to give β-amino acid esters in high yield. The overall green chem. process involves converting terminal alkynes into unusual β-amino acid esters with only water generated as an essential byproduct. This catalytic system has also been applied to the hydroformylation of simple 1,2-disubstituted unsaturated esters, which were hydroformylated with excellent α-selectivity and good chemoselectivity.
