The design, development and application of an efficient procedure for the concise synthesis of the 1,3-syn- and anti-tetrahydropyrimidine cores of manzacidins are reported. The intramolecular allylic substitution reaction of a readily available joint urea-type substrate enables the facile preparation of both diastereomers in high yields. The practical application of this approach is demonstrated in the efficient and modular preparation of the authentic heterocyclic cores of manzacidins, structurally unique bromopyrrole alkaloids of marine origin. Additional features of this route include the stereoselective generation of the central amine core with an appending quaternary center by an asymmetric addition of a Grignard reagent to a chiral tert-butanesulfinyl ketimine following an optimized Ellman protocol and a cross-metathesis of a challenging homoallylic urea substrate, which proceeds in good yields in the presence of an organic phosphoric acid.

A ruthenium-catalyzed transfer hydrogenation of olefins utilizing formic acid as a hydrogen donor is described. The application of commercially available alkylidene ruthenium complexes opens access to attractive C(sp3)-C(sp3) bond formation in an olefin metathesis/transfer hydrogenation sequence under tandem catalysis conditions. High chemoselectivity of the developed methodology provides a remarkable synthetic tool for the reduction of various functionalized alkenes under mild reaction conditions. The developed methodology is applied for the formal synthesis of the drugs pentoxyverine and bencyclane.

A Hoveyda-type catalyst for olefin metathesis was synthesized and covalently attached via an amide bond to four different solid supports. One of these supports was a home-made hybrid silica support, where an ultra-thin copolymer of poly(styrene) and poly(acrylamide) was grafted on. The three other supports were commercially available, namely HypoGel 400, PEGA and Trisoperl. It was demonstrated that the catalysts were active in ring closing metathesis (RCM) reactions as well as in cross metathesis (CM) and ring opening metathesis (ROM) reactions, but the activity of the catalyst was highly dependent on the nature of the support.

Less is more: It is much less efficient to synthesize both components of a multivalent recognition site separately than it is to use one multivalent component to act as a template for the catalytically orchestrated construction of the other component, as demonstrated by the formation of the mechanically interlocked, triply threaded molecular bundle shown. The situation is reiniscent of nature.

An efficient synthetic route to a novel macrocyclic aryl alpha-diimine ligand bearing C6 hydrocarbon bridges connecting the aryl ortho positions is described. Pd(II) and Ni(II) complexes with the new macrocyclic ligand (10 and 14) were successfully synthesized and characterized. The X-ray crystal structures of complexes 10 and 14 show that the complexes exhibit coordination geometry similar to that of their acyclic analogues and the alkyl bridges do not introduce significant ring strain into the complexes. The preactivated Pd(II) complex 12 and the allyl nickel complex 14 were tested for ethylene polymerization. Potential reasons for the low catalytic activities are discussed.

This article describes new selectivities for Grubbs’ first and second generation catalysts when occluded in a hydrophobic matrix of polydimethylsiloxane (PDMS). Occlusion of catalysts in mm-sized slabs of PDMS is accomplished by swelling with methylene chloride then removing the solvent under vacuum. The catalysts are homogenously dissolved in PDMS yet remain catalytically active. Many substrates that react by olefin metathesis with Grubbs’ catalysts freely dissolved in methylene chloride also react by olefin isomerization with occluded catalysts. Eleven examples of substrates that exhibit dual reactivity by undergoing olefin isomerization with occluded catalysts and olefin metathesis with catalysts dissolved in methylene chloride are reported. Most of these substrates have olefins with allylic phosphine oxides, carbonyls, or ethers. Control experiments demonstrate that isomerization is occurring in the solvent by decomposition of the catalyst from a ruthenium carbene to a proposed ruthenium hydride. This work was extended by heating occluded Grubbs’ first generation catalyst to 100 C in 90% MeOH in H2O in the presence of various alkenes to transform the Grubbs’ catalyst into an isomerization catalyst for unfunctionalized olefins. This work demonstrates that occlusion of organometallic catalysts in PDMS has important implications for their reactions and can be used as a method to control which reactions they catalyze.
