(Figure Presented) A 4 nm-sized covalent organic capsule having 24 pyridyl groups was synthesized in extremely high yield (43% in three steps) using an octahedron-shaped metallocapsule as a template molecule. The entity was fully characterized by NMR and MALDI-TOF MS measurements. N-Methylation of the 24 pyridyl groups of the organic capsule produced a 5 nm-sized polycationic capsule, which is larger than the neutral precursory capsule because of the electrostatic repulsion between the positive charges on the pyridinium groups of the capsule.

Four partially protected stereoisomeric cyclopentenetriols 5, 10, 15 and 21 have been prepared by ring-closing metathesis of carbohydrate-derived 1,6-dienes. The presence of a differentiated allylic alcohol in the cyclopentenetriols allows a variety of synthetic transformations, underlining the synthetic use of the prepared cyclopentenetriol derivatives as chiral building blocks.

Molecular scaffolds of polycyclic aromatic hydrocarbons can serve as unique tools to control the molecular and electronic structure of coordination compounds. Herein, we report the synthesis and properties of a Hoveyda-Grubbs metathesis catalyst bearing a chelating benzylidene ligand assembled on peri-substituted naphthalene. In contrast to other reported naphthalene-based complexes (Barbasiewicz, M. and Grela, K.Chem. Eur. J. 2008, 14, 9330-9337), it exhibits a very fast initiation behavior, attributed to a distorted molecular structure and reduced pi-electron delocalization within the chelate ring.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu.

Whereas the boomerang ligand of Hoveyda-Grubbs pre-catalysts can be modified by attachment of a pyridinium tag to its benzylidene moiety, a precise adjustment of the length of the spacer allows the optimum balance to be reached between the activity of the catalyst and its recoverability, exceeding 98% after 6 catalytic runs in the best case.

The first total synthesis of the marine dolabellane diterpene (+)-4,5-deoxyneodolabelline (1) has been accomplished. The highly efficient approach is characterized by the convergent assembly of dihydropyrans 2ab and cyclopentylsilanes 3ab. Allylic silane 3a was prepared from 2- methyl-2-cyclopentenone via a copper-catalyzed 1,4-addition followed by diastereoselective alkylation of the resulting enolate. A chemical resolution of racemic cyclopentanone 8 was effected by (S)-CBS-catalyzed borohydride reduction. Direct hydroxymethylation of the enantioenriched ketone 8 to form allylic alcohol 14 was achieved by a Stille palladium-catalyzed cross-coupling from the cyclopentenyl triflate 13. Treatment of the corresponding allylic phosphate 15 with trimethylsilylcopper reagent provided for displacement with allylic transposition yielding the exocyclic allylsilane 3a with excellent diastereoselectivity. Dihydropyrans 2a and 2b were prepared from optically pure acyclic acetals via ring-closing metathesis. Coupling of 3a and 2a or 2b via the carbon-Ferrier protocol gave trans-2,6-disubstituted dihydropyrans 30 and 35 with complete stereoselectivity. Vanadium-based pinacol coupling reactions were explored for closure of the mediumsized carbocycle to yield syn-diol 33. X-ray diffraction studies of the monobenzoate 34 have provided unambiguous stereochemical assignments. Substantial ring strain accounted for the lack of alkene products typical of reductive elimination using TiCl3 and zinc-copper couple (McMurry) conditions leading to 37. Finally, the natural product 1 was obtained via Swern oxidation of the diol 37.

The first ansa-nickelocenes, [Ni(eta5,eta5-C 5H4-CH2-CH=CH-CH2-C 5H4)] (4) and [Ni(eta5,eta5- C5H4(CH2)2-CH=CH-(CH 2)2-C5H4)] (5), and a bridged binickelocene, [Ni2(eta5,eta5-C 5H4-(CH2)2-CH=CH(CH 2)2-CsH4)2] (6), were prepared by alkene metathesis of 1,1?-disubstituted nickelocenes. Compound 4 reacts with hydrogen to yield ansa-nickelocene 7, bearing the saturated bridge. The new compounds were characterized by UV-vis, IR, MS, 1H NMR, magnetic susceptibility, and electrochemical measurements. Crystal and molecular structures of 4, 6, and 7 were determined by single-crystal X-ray analysis. These measurements show that the studied ansa-nickelocenes exhibit properties similar to those of nickelocene.

An efficient 1,4-hydrovinylative cyclization reaction of triynes and tetraynes catalyzed by ruthenium alkylidene complexes under ethylene is described. The regioselectivity of vinyl group incorporation can be controlled by the nature of the substituent on the alkyne, and the Grubbs second-generation catalyst is the most effective among typical ruthenium alkylidene complexes.
