One-Step Multifunctionalization of Random Copolymers via Self-Assembly

A novel methodology for random copolymer functionalization based on a noncovalent, one-step, multifunctionalization strategy has been developed. Random copolymers possessing both palladated-pincer complexes and diaminopyridine moieties (hydrogen-bonding entities) have been synthesized using ring-opening metathesis polymerization. Noncovalent functionalization of the resultant copolymers is accomplished via (1) directed self-assembly, (2) multistep self-assembly, and (3) one-step orthogonal self-assembly. This system shows complete specificity of each recognition motif for its complementary unit, with no observable changes in the association constants regardless of the degree of functionalization.

Enyne ring-closing metathesis on heteroaromatic cations

Cationic heteroaromatic enynes have been employed as substrates in enyne ring-closing metathesis, under an atmosphere of ethylene and using the Hoveyda-Grubbs catalyst, for the first time; the reaction affords new 1-vinyl- and 2-vinyl-substituted 3,4-dihydroquinolizinium salts, useful precursors for biologically relevant cations based on the quinolinizium system.

A straightforward approach towards cyclic peptides via ring-closing metathesis – Scope and limitations

N- and C-terminal diallylated peptides are obtained by several approaches, such as peptide Claisen rearrangement, N- and O- allylation, and the Ugi reaction of allyl-protected components. These diallylated peptides are suitable substrates for ring-closing metathesis and the success of this cyclisation was investigated with respect to the ring size, the position of the allyl moieties and the reaction parameters. In general, excellent yields are obtained for cyclisation of allyl glycine subunits and N-allylated amides, while allyl esters and allyl carbamates often presented serious problems. However, yields of up to 73% were obtained under optimised conditions, and the new generated double bond is formed with excellent trans-selectivity.

The reactions of 3-alkylindoles with cyclopropanes: An unusual rearrangement leading to 2,3-disubstitution

Indoles that bear an alkyl substituent in the 3-position, when treated with cyclopropanediesters, typically undergo a [3 + 2]-annulation reaction in a kinetically controlled process (1?4). If the reaction is performed at elevated temperatures for a longer period of time, a rearrangement of the putative intermediate 3 occurs in which the alkylating species undergoes a migration to the 2-position followed by loss of a proton to reform the benzopyrrole ring. The yields range from 78 to 10%. If a 3-allylindole is used in combination with a cyclopropanediester, which is further substituted with an alkenyl moiety, the product is an effective ring closing metathesis substrate and can be converted to the 1,3,3a,4,5,6-hexahydro-1H-pyrido[3,2,1-jk]carbazole system. A mechanistic discussion of the rearrangement process is presented.

New approaches to olefin cross-metathesis

New methodology for the selective cross-metathesis (CM) of terminal olefins employing ruthenium benzylidene 1 is described. CM with symmetric internal olefins was found to provide a useful means for homologating terminal olefins to protected allylic alcohols, amines, and esters. Due to the limited commercial availability of symmetric internal olefins, a two-step CM procedure was developed in which terminal olefins were first homodimerized prior to the CM reaction. Terminal olefins with allylic methyl substituents were observed to provide CM products in diminished yield albeit with markedly improved trans-selectivity. Reaction rates were measured for CM reactions utilizing butenediol and allyl alcohol derivatives, and the results demonstrated distinct advantages in reaction rate and stereoselectivity for reactions employing the disubstituted olefins. In the course of studies of substrates with allylic oxygen substituents, a new CM application was discovered involving the metathesis of acrolein acetal derivatives with terminal olefins. Acrolein acetals, including asymmetric variants derived from tartaric acid, proved to be exceptionally robust and trans-selective CM substrates. In related work, a pinacol-derived vinyl boronate was also found to be a reactive CM partner, providing a novel means for converting terminal olefins into precursors for the Suzuki coupling reaction.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 172222-30-9 is helpful to your research., Reference of 172222-30-9

Dimerization of diruthenium coordination compounds via olefin metathesis

Diruthenium compounds containing an omega-alkene-alpha-carboxylate ligand, Ru2Cl[D(3,5-Cl2Ph) F]3[O 2C(CH2)nCH=CH2] [n = 1 (1a) and 2 (1b)], were prepared from the reactions between Ru2Cl[D(3,5-Cl 2Ph)F]3(O2CCH3) [D(3,5-Cl 2Ph)F = N,N?-bis-(3,5-dicholorophenyl)formamidinate] and omega-alkene-alpha-carboxylic acids. Both compounds 1a and 1b undergo olefin cross-metathesis reactions catalyzed by (Cy3P)2Cl 2Ru-(=CHPh) to afford the dimerized compounds [Ru2Cl{D(3, 5-Cl2Ph)F}3]2[mu-O2C(CH 2)nCH=CH(CH2)nCO2] [n = 1 (2a) and 2 (2b)]. Molecular structures of compounds 1a/1b and 2a/2b were established by X-ray diffraction studies, which revealed the formation of trans product only in the case of shorter tether (2a) and a mixture of cis-/trans isomers in the case of longer tether (2b).
