Three-step metal-promoted allene-based preparation of Bis(heterocyclic) cyclophanes from carbonyl compounds

A straightforward metal-mediated method for the synthesis of bis(dihydrofuryl) cyclophane scaffolds from carbonyl compounds has been developed. The combination of the dihydrofuran moiety with different heterocycles such as beta-lactams and sugars allows high levels of skeletal diversity. The process comprises indium-promoted one-pot carbonyl bis(allenylation) and gold- or palladium-catalyzed double cyclization in the resulting bis(allenols), followed by selective ruthenium-catalyzed macrocyclization. In some cases, the method has been successfully applied to the synthesis of the challenging Z-isomers. The E- versus Z-stereochemistry of the metathesis-formed double bonds could not be assigned taking into consideration the usual coupling constants criteria, but a diagnostic based on the chemical shifts of the two olefinic protons located at the macrocyclic double bond was established.

Alkene Metatheses in Transition Metal Coordination Spheres: Effect of Ring Size and Substitution on the Efficiencies of Macrocyclizations that Join Trans Positions of Square-Planar Platinum Complexes

Reactions of KPPh2 and Br(CH2)nCH=CH 2 give the phosphines PPh2(CH2) nCH=CH2 (n = a, 4; b, 6; c, 8; d, 9; 95-41%), which are combined with the platinum tetrahydrothiophene complex [Pt(mu-Cl)(C 6F5)(S(CH2CH2-)2)] 2 to give trans-(Cl)(C6F5)Pt(PPh 2(CH2)nCH=CH2)2 (3a-d, 71-54%). When treated with Grubbs’ catalyst, ring-closing alkene metatheses occur to give 13- to 23-membered macrocycles with trans-spanning diphosphine ligands (96-85%, including some dimeric or oligomeric byproducts). The mixtures of C=C isomers are hydrogenated (1 atm, 10% Pd/C) to give trans-(Cl)(C 6F5)Pt(PPh2(CH2) 2n+2PPh2) (6a-d), which are isolated in 72-50% yields. Comparable results are obtained with (1) the second-generation dihydroimidazolylidene Grubbs’ catalyst and (2) a series of compounds derived from the dimethylated phosphine Ph2P(CH2) 2C(CH3)2(CH2)3CH=CH 2, in turn prepared by sequential reactions of BrCH 2CH2C(CH3)2CH2CH 2Br with BrMgCH2CH=CH2/Li2CuCl 4 and KPPh2. The crystal structures of 6a-d are analyzed, but no special features that would promote intramolecular macrocyclizations are noted. A reaction of [Pt(mu-Cl)(C6F5)(S(CH 2CH2-)2)]2 and the diphosphine Ph2P(CH2)14PPh2 leads to a multitude of products and little 6b (<15%). Do you like my blog?

Stereoselective synthesis of E,Z-configured 1,3-dienes by ring-closing metathesis. Application to the total synthesis of lactimidomycin

Strategic positioning of a silyl group on the diene unit of a diene-ene substrate allows rigorous regio- and stereocontrol to be exerted during metathesis-based macrocyclization reactions. The versatility of this concise approach to E,Z-configured 1,3-dienes of ring sizes of 12 or larger is demonstrated by an application to the total synthesis of lactimidomycin, a potent translation and cell-migration inhibitor.

A Thermo- and Photo-Switchable Ruthenium Initiator for Olefin Metathesis

A ruthenium carbene complex bearing azobenzene functionality is reported. The complex exists in the form of two isomers differing by the size of the chelate ring. Both isomers were isolated by applying kinetic or thermodynamic control during the synthesis and characterized by X-ray diffraction analysis. The isomerization of the complex was studied by UV/Vis spectroscopy. The stable isomer was tested as a catalyst in olefin metathesis. The complex was activated at about 100C to promote ring-closing and ring-opening polymerization metathesis reactions. The activation took place also at room temperature under middle ultraviolet radiation.

Synthesis of 1,2-Disubstituted Cyclopentadienes from Alkynes Using a Catalytic Haloallylation/Cross-Coupling/Metathesis Relay

A three-step method based on Pd-catalyzed haloallylation of alkynes, Pd-catalyzed cross-coupling, and Ru-catalyzed ring-closing metathesis constitutes a new and short approach to variety of 1,2-substituted cyclopentadienes. The scope of the method is broad with respect to different substituents (alkyl, aryl, metallocenyl, and other substituents as well as their combinations are tolerated), and all steps proceeded with sensible yields. As a demonstration of product utility, several of the prepared cyclopentadienes were converted into the corresponding ferrocenes.

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 246047-72-3 is helpful to your research., 246047-72-3

A bicyclo-type cage-shaped compound consisting of three sexithiophenes was successfully synthesized and characterized by NMR, HRMS, and X-ray crystallographic analysis. The strained cage architecture was reflected in the blue-shifted absorption spectrum relative to its linear analogue. Intramolecular interaction between three-dimensionally fixed sexithiophenes was suggested by electrochemical analysis.
