The synthesis and characterization of monomeric and dendritic Grubbs II and Hoveyda-Grubbs II-based complexes are reported. These complexes were synthesized via a route based on the connection of monomeric or dendritic N-alkyl-N?-mesitylimidazol-2-ylidene pre-ligands to Grubbs I or Hoveyda-Grubbs I complexes. The immobilization of a modified Grubbs II type catalyst on a G0 carbosilane dendrimer was successfully carried out. Together with monomeric Grubbs II and Hoveyda-Grubbs-analogs and several commercially available olefin metathesis catalysts, the soluble, homogeneous G0-dendritic Grubbs II complex was tested as catalyst in the ring closing metathesis of diethyl diallylmalonate. The immobilized complex proved to outperform its monomeric analog in this reaction at room temperature, whereas it was found to be slightly slower at reflux temperature.

A one-pot reaction to synthesize functionalized 2H-azirines through visible-light-mediated ring contraction and olefin metathesis of isoxazoles is described. Hoveyda-Grubbs II catalyst was found to function as a photocatalyst for these transformations, allowing these processes to be carried out in a one-pot manner. This study offers a new entry for the application of Grubbs catalysts as efficient photocatalysts and the possibilities of carrying out other photoreactions and olefin metathesis in a one-pot process.

The synthesis of the marine neurotoxin azaspiracid-1 has been accomplished. The individual fragments were synthesized by catalytic enantioselective processes: A hetero-Diels-Alder reaction to afford the E- and HI-ring fragments, a carbonyl-ene reaction to furnish the CD-ring fragment, and a Mukaiyama aldol reaction to deliver the FG-ring fragment. The subsequent fragment couplings were accomplished by aldol and sulfone anion methodologies. All ketalization events to form the nonacyclic target were accomplished under equilibrating conditions utilizing the imbedded configurations of the molecule to adopt one favored conformation. A final fragment coupling of the anomeric EFGHI-sulfone anion to the ABCD-aldehyde completed the convergent synthesis of (+)-azaspiracid-1.

Simple models of the spiroimine core of (-)-gymnodimine A have been synthesized in racemic and optically active forms. The quaternary carbon of the racemic spiroimines was created by Michael addition of a beta-ketoester to acrolein, whereas the asymmetric allylic alkylation of the same beta-ketoester was used to access the spiroimines in an enantioselective fashion. Both racemic and enantio-enriched mixtures were tested for their biological activities on Xenopus oocytes either expressing (human alpha4beta2) or having incorporated (Torpedo alpha12betagammadelta) nicotinic acetylcholine receptors (nAChRs). These spiroimine analogs of (-)-gymnodimine A inhibited acetylcholine-evoked nicotinic currents, but were less active than the phycotoxin. Our results reveal that the 6,6-spiroimine moiety is important for the blockade of nAChRs and support the hypothesis that it is one of the pharmacophores of this group of toxins.

Ruthenium benzylidene complexes are well-known as olefin metathesis catalysts. Several reports have demonstrated the ability of these catalysts to also facilitate atom transfer radical (ATR) reactions, such as atom transfer radical addition (ATRA) and atom transfer radical polymerization (ATRP). However, while the mechanism of olefin metathesis with ruthenium benzylidenes has been well-studied, the mechanism by which ruthenium benzylidenes promote ATR reactions remains unknown. To probe this question, we have analyzed seven different ruthenium benzylidene complexes for ATR reactivity. Kinetic studies by 1H NMR revealed that ruthenium benzylidene complexes are rapidly converted into new ATRA-active, metathesis-inactive species under typical ATRA conditions. When ruthenium benzylidene complexes were activated prior to substrate addition, the resulting activated species exhibited enhanced kinetic reactivity in ATRA with no significant difference in overall product yield compared to the original complexes. Even at low temperature, where the original intact complexes did not catalyze the reaction, preactivated catalysts successfully reacted. Only the ruthenium benzylidene complexes that could be rapidly transformed into ATRA-active species could successfully catalyze ATRP, whereas other complexes preferred redox-initiated free radical polymerization. Kinetic measurements along with additional mechanistic and computational studies show that a metathesis-inactive ruthenium species, generated in situ from the ruthenium benzylidene complexes, is the active catalyst in ATR reactions. Based on data from 1 H, 13C, and 31P NMR spectroscopy and X-ray crystallography, we suspect that this ATRA-active species is a RuxCly(PCy3)z complex.

Novel regioselective ring closing ene-yne metathesis provided an efficient access to different substituted 1-benzazepine scaffolds. The reported synthetic approach could also be used as a powerful tool for the selective formation of a highly functionalizable 2-benzazepine core. This synthetic protocol was even proved to be an efficient way to obtain a functionalizable benzazocine derivative. By modifying the structure of the starting materials, the optimized cyclization finally proved to be a suitable technique to obtain five- and six-membered lactams, enhancing the synthetic application of our method. Five- and six-membered lactams were efficiently prepared by ring-closing metathesis involving the loss of ethylene moiety and affording highly functionalizable compounds showing both electron-withdrawing substituents and electron-donor groups.
