Concise synthesis of broussonone A

A concise and expeditious approach to the total synthesis of broussonone A, a p-quinol natural compound, has been developed. The key features of the synthesis include the Grubbs II catalyst mediated cross metathesis of two aromatic subunits, and a chemoselective oxidative dearomatizationin the presence of two phenol moieties. Especially, optimization associated with the CM reaction of ortho-alkoxystyrenes was also studied, which are known to be ineffective for Ru-catalyzed metathesis reactions under conventional reaction conditions because ortho-alkoxy group could coordinate to the ruthenium center, resulting in the potential complication of catalyst inhibition.

New synthesis and thermal studies of palladacycloalkanes and their precursors

A series of new palladacycloalkanes of formula cis-[PdL2(CH2)n] (9. n = 6, L = PPh3; 10. n = 6, L2 = dppe; 11. n = 8, L = PPh3; 12. n = 8, L2 = dppe) have been prepared by two routes. In the first route, the precursor bis(1-alkenyl) complexes cis-[PdL2((CH2)nCH{double bond, long}CH2)2] (1. n = 2, L = PPh3, 2. n = 2, L2 = dppe, 3. n = 3, L = PPh3, 4. n = 3, L2 = dppe) were allowed to react with Grubb’s 2nd generation catalyst to give the palladacycloalkenes, cis-[PdL2(CH2)nCH{double bond, long}CH(CH2)n] (5. n = 2, L = PPh3, 6. n = 2, L2 = dppe, 7. n = 3, L = PPh3, 8. n = 3, L2 = dppe), which were then hydrogenated to the palladacycloalkanes, 9-12. In the second route, the di-Grignard reagents BrMg(CH2)nMgBr (n = 6, 8) were reacted with the palladium complex [PdCl2(COD)] followed by immediate ligand displacement to form the respective palladacycloalkanes 10 and 12. The complexes obtained were characterized by a range of spectroscopic and analytical techniques. Thermal decomposition studies were carried out on the palladacycloalkanes 9-12 and the main organic products shown to be 1-alkenes and 2-alkenes.

Chiral Br¡ãnsted Acid-Catalyzed Asymmetric Allyl(propargyl)boration Reaction of ortho-Alkynyl Benzaldehydes: Synthetic Applications and Factors Governing the Enantioselectivity

Chiral Br¡ãnsted acid-catalyzed allyl(propargyl)boration of ortho-alkynyl benzaldehydes gives rise to omega-alkynyl homoallylic(homopropargylic)alcohols that can be further transformed to complex molecular scaffolds via subsequent hydroalkoxylation, ring-closing enyne metathesis (RCEYM), or intramolecular Pauson-Khand reaction (PKR). Optimizations of each two-step transformation is reported. A strong dependence between enantioselectivities and the nature of the substitution at the alkynyl moiety is observed, showcasing that the triple bond is not merely a spectator in this transformation. Density functional theory (DFT) calculations (M06-2X/6-311+G(d,p)-IEFPCM//B3LYP/6-31G(d)) show that this dependence is the result of the steric and electronic properties of the alkyne substituent.

Fully backbone degradable and functionalizable polymers derived from the ring-opening metathesis polymerization (ROMP)

Functionalized degradable ROMP (ring-opening metathesis) polymers and methods, starting monomers and synthetic monomeric and polymeric intermediates for preparation of such functionalized polymers. More specifically, monomers having a bicyclic oxazinone structure, a bicyclic urea, or a heteronorbornene core structure, among others, have been found to be substrates for ROMP polymerization. ROMP polymers prepared from these monomers have been found to be both acid and base labile. Additionally, the monomers can be chemically modified at a site distal to the polymerizable moieties and bridgehead carbons. The properties of the resulting polymers and copolymers can be tailored without destabiling the monomer. Polymers and copolymers of the invention are degradable but have a glass temperature of 100 C. or more.

Preparation of seven-membered carbocycles using ring-closing metathesis reaction and application to syntheses of tormesol and cyathane skeleton

Various precursors were synthesized and were reacted with the Grubbs reagent as well as the second generation Grubbs reagent to cyclize them into seven-membered carbocycles with di- or tri-substituted double bonds. These reactions were used to synthesize (-)-tormesol, which is an enantiomer of sphenolobane-type diterpene that was isolated from Halimium viscosum, and a basic skeleton of cyathane-type diterpene.

Decomposition of Olefin Metathesis Catalysts by Br¡ãnsted Base: Metallacyclobutane Deprotonation as a Primary Deactivating Event

Br¡ãnsted bases of widely varying strength are shown to decompose the metathesis-active Ru intermediates formed by the second-generation Hoveyda and Grubbs catalysts. Major products, in addition to propenes, are base¡¤HCl and olefin-bound, cyclometalated dimers [RuCl(kappa 2-H2IMes-H)(H2C=CHR)]2 Ru-3. These are generated in ca. 90% yield on metathesis of methyl acrylate, styrene, or ethylene in the presence of either DBU, or enolates formed by nucleophilic attack of PCy3 on methyl acrylate. They also form, in lower proportions, on metathesis in the presence of the weaker base NEt3. Labeling studies reveal that the initial site of catalyst deprotonation is not the H2IMes ligand, as the cyclometalated structure of Ru-3 might suggest, but the metallacyclobutane (MCB) ring. Computational analysis supports the unexpected acidity of the MCB protons, even for the unsubstituted ring, and by implication, its overlooked role in decomposition of Ru metathesis catalysts.
