Flexible and enantioselective access to jaspine B and biologically active chain-modified analogues thereof

Whereas the all-cis tetrahydrofuran framework of the cytotoxic anhydrophytosphingosine jaspine B is considered as a relevant pharmacophore, little is known about the influence of the aliphatic chain of this amphiphilic molecule on its activity. We developed a synthetic strategy allowing flexible introduction of various lipophilic fragments in the jaspine’s skeleton. The route was validated with two distinct approaches to jaspine B. Five chain-modified analogues were also prepared. Biological evaluation of these derivatives demonstrated a good correlation between their cytotoxicity and their capacity to inhibit conversion of ceramide into sphingomyelin in melanoma cells. A series of potent and selective inhibitors of sphingomyelin production was thus identified. Furthermore, the good overall potency of an omega-aminated analogue allowed us to dissociate of the pharmacological action of jaspine B from its amphiphilic nature.

Selective synthesis of multisubstituted olefins utilizing gem – And vic -diborylated vinylsilanes prepared by silylborylation of an alkynylboronate and diborylation of alkynylsilanes

The synthesis of a series of gem- and vic-diborylated vinylsilanes was accomplished via highly selective transition-metal-catalyzed syn-dimetalation to the alkynylmetal species. This protocol served as a general synthetic method toward regio- and stereodefined multisubstituted olefins. The key steps are the diastereoselective Suzuki-Miyaura cross-coupling reactions of gem- and vic-diborylated vinylsilanes, in which the two boron groups showed discrete reactivities to afford diverse precursors of multisubstituted olefins.

Synthesis of 2H-chromenes through the reduction of chromones with 9-BBN

Chromones were regioselectively reduced to 2H-1-benzopyrans through the 1,2-addition of 9-borabicyclo-[3.3.1]nonane. Although transition-metal complexes did not have a catalytic effect on the reaction, only by using palladium(II) chloride, could both 2H-1-benzopyran and dihydro-1-benzopyran be obtained to a similar extent. Also, the reduction of chromone using other organoboranes led not to 2H-1-benzopyran, but rather to chromanone through the reduction of only an olefin moiety.

Novel organometallic building blocks for molecular crystal engineering

The competition between the hydrogen-bonding interactions of the (B)O-H…O(B) and (B)O-H…N types in the cases of crystalline 1 and 2 has been investigated. The B(OH)2 group provides two hydrogen bonding donor groups and two acceptors, forming mainly cyclic hydrogen-bonded systems in topological analogy with a primary amido group. Compounds 4, 6, and 7 are examples of neutral disubstituted pyridyl and pyrimidyl ferrocenyl complexes with potentials as supramolecular ligands.

Application of 72287-26-4, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 72287-26-4, Name is [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II),introducing its new discovery.

Palladium (II) complexes with mono-oxide 1,1?-bis(diphenylphosphino) metallocene ligands [Fe(eta5-C5Me4PPh 2)(eta5-C5Me4P{O}Ph2)] and [Os(eta5-C5H4PPh2) (eta5-C5H4P{O}Ph2)]

The monoxides [Fe(eta5-C5Me4PPh 2)(eta5-C5Me4P{O}Ph2)] (1) and [Os(eta5-C5H4PPh2) (eta5-C5H4P{O}Ph2)] (2) have been prepared by treatment of the corresponding diphosphines with CCl4 and methanol. These ligands react with [Pd(PhCN)2Cl2] to give dichloride complexes of different structure. The dimeric complex [{Os(eta5-C5H4PPh2) (eta5-C5H4P{O}Ph2)}PdCl(mu-Cl)] 2 (4) contains the monodentate P-coordinated osmocene ligand with the free P{O}Ph2 group, while the octamethylferrocene ligand gives the chelate k2-P,O complex [{Fe(eta5-C5Me 4PPh2)(eta5-C5Me 4P{O}Ph2)}PdCl2] (3). The structures of 3 and 4 have been determined crystallographically. Treatment of 3 and 4 with silver salts in CH2Cl2 or acetonitrile leads to the corresponding dicationic complexes[{M(eta5-C5R4PPh 2)(eta5-C5R4P{O}Ph 2)}Pd(MeCN)x]2+ (5, M = Fe, R = Me; 6, M = Os, R = H). Complex 5 decomposes upon isolation, in contrast 6 is rather stable, probably due to Os-Pd bonding. The dichlorides 3 and 4 catalyze catalytic amination of p-bromotoluene with N-(4-tolyl)morpholine with lower activity than (dppf)PdCl2, however they perform comparable to (dppf)PdCl 2 activity in coupling of p-bromotoluene with p-methoxyphenyl boronic acid.
