Unified strategy for the synthesis of the “miscellaneous” Lycopodium alkaloids: Total synthesis of (¡À)-lyconadin A

Total synthesis of the Lycopodium alkaloid lyconadin A was achieved in 18 steps starting from a readily available vinylogous ester and bromopicoline. The key step in the total synthesis is a proximity-driven oxidative C-N bond-forming reaction that yields the lyconadin pentacycle from a tetracyclic precursor. The key tetracycle, which has been prepared for the first time, is a versatile intermediate that may be utilized for the total synthesis of a variety of Lycopodium alkaloids. Critical to the success of this plan was the efficient preparation of a pyridine-annulated cycloheptadiene tricycle that promises to be a general strategy to access a variety of seven-membered ring containing natural products.

Preparation and characterization of novel poly(alkylidenamine) nitrile ruthenium metallodendrimers

Complete functionalization of N,N,N?,N?-[tetrakis(cyanoethyl)- hexamethylenediamine] [N=C(CH2)2]2N(CH 2)6N[(CH2)2-C=N]2 (4) and N,N,N’,N’-[tetrakis(cyanoethoxypropyl)hexamethylenediamine] [N=C(CH 2)2O(CH2)3]2N(CH 2)6N[(CH2)3-O(CH2) 2C=N]2 (7) with the organometallic moiety [Ru(eta5-C5H5)(PPh3) 2Cl] and the five-coordinate cis-[RuCl(dppe)2]-[PF 6] [dppe = 1,2-bis(diphenylphosphanyl)ethane] was attained, with good yield, respectively, by treating the metallofragment with the core in methanol (at room temperature and in presence of T1PF6 as a chloride abstractor) and in 1,2-dichloroethane (under reflux). These novel nitrile-functionalized poly(alkylidenamine) dendrimers peripherally functionalized with the ruthenium moieties [Ru(eta5-C 5H5)(PPh3)2]+ and [RuCl(dppe)2]+ (8-11) were fully characterized by NMR (1H, 13C, 31P), TOF-MS and FTIR. The present results represent a step forward in the knowledge of the most adequate synthetic strategy for total coordination of poly(alkylidenamine) nitrile core derivatives to the different ruthenium complex moieties and confirm the versatility of these systems as building blocks in metallodendrimer chemistry.

Gold(I)-catalyzed coupling reactions for the synthesis of diverse small molecules using the build/couple/pair strategy

The build/couple/pair strategy has yielded small molecules with stereochemical and skeletal diversity by using short reaction sequences. Subsequent screening has shown that these compounds can achieve biological tasks considered challenging if not impossible (‘undruggable’) for small molecules. We have developed gold(I)-catalyzed cascade reactions of easily prepared propargyl propiolates as a means to achieve effective intermolecular coupling reactions for this strategy. Sequential alkyne activationof propargyl propiolates by a cationic gold(I) catalyst yields an oxoca rbenium ion that we previously showed is trapped by C-based nucleophilesat an extrannular site to yield alpha-pyrones. Here, we report O-base d nucleophiles react by ring opening to afford a novel polyfunctional product. In addition, by coupling suitable building blocks, we subsequently performed intramolecular pairing reactions that yield diverse and complex skeletons. These pairing reactions include one based on a novel aza-Wittig-6?-electrocyclization sequence and others based on ring-closing metathesis reactions.

Ruthenium-catalyzed alkenylative cyclization via insertion of alkene into ruthenacyclopentene

A novel rumenium-catalyzed alkenylative cyclization of enyne was developed. When an enyne was reacted with Cp*RuCl(cod) under an atmosphere of ethylene, ethylene was inserted into the ruthenium-sp2 carbon bond of ruthenacyclopentene derived from enyne and the low-valent ruthenium complex to afford ruthenacycloheptene, and beta-hydrogen elimination followed by reductive elimination occurred to give a cyclic compound having a diene moiety. In this reaction, acrylaldehyde could be inserted into ruthenacyclopentene instead of ethylene. Various carbo- and heterocyclic compounds could be obtained in high yields.

Chelated ruthenium catalysts for Z -selective olefin metathesis

We report the development of ruthenium-based metathesis catalysts with chelating N-heterocyclic carbene (NHC) ligands that catalyze highly Z-selective olefin metathesis. A very simple and convenient procedure for the synthesis of such catalysts has been developed. Intramolecular C-H bond activation of the NHC ligand, promoted by anion ligand substitution, forms the appropriate chelate for stereocontrolled olefin metathesis.
