A new TiIII-mediated reductive epoxide-opening/ Beckwith?Dowd rearrangement process efficiently assembles the bicyclo[3.2.1]octane framework of highly oxidized grayanane diterpenoids. By incorporation of a Cu(tbs)2-catalyzed (tbs=N-tert-butylsalicylaldiminato) intramolecular cyclopropanation, a diastereoselective oxidative dearomatization-induced Diels?Alder cycloaddition and a MeReO3-catalyzed Rubottom oxidation, this approach has enabled the first total syntheses of rhodomolleins XX and XXII in 23 and 22 steps, respectively.

Thymidine deoxyoligonucleotides having a 5′-deoxy-5′-methylidyne phosphonate internucleotide linkage were synthesized. Relative to natural DNA, these oligomers were nuclease resistant and formed duplexes with reduced stability.

A series of NNN-pincer iron complexes bearing ketimine-type iminobipyridene (BPI) ligands were prepared. These iron complexes were effective catalysts for the hydrosilylation of olefins using primary, secondary, and tertiary silanes. The effect of the substituents on the imino carbon on the catalytic activity was examined, and it was found that an appropriate combination of the imino carbon and imino nitrogen substituents led to complexes with quite high catalytic activity: the turnover number achieved was up to 42000. These iron catalytic systems provide a low-cost and promising alternative to currently employed precious metal systems for the hydrosilylation of olefins.

Novel binaphthyl-based chiral bifunctional organocatalysts were designed, synthesized and successfully applied to the asymmetric List-Lerner-Barbas aldol reaction in the presence of water. These organocatalysts were found to be effective catalysts for the reactions of symmetrical, unsymmetrical and cyclic ketones with different aldehydes to give the corresponding aldol products with higher yields (up to 98%) and very good ee’s up to 99%. The catalytic system leads to higher yields and selectivities than the previously reported well-known proline based organocatalysts. In addition to the effect of solvent, additives, catalyst concentration, temperature and the substrate scope of the reactions were also investigated.

Identification of a novel catalyst-allenoate pair allows enantioselective [2+2] cycloaddition of alpha-methylstyrene. To understand the origin of selectivity, a detailed mechanistic investigation was conducted. Herein, two competing reaction pathways are proposed, which operate simultaneously and funnel the alkenes to the same axially chiral cyclobutanes. In agreement with the Woodward-Hoffmann rules, this mechanistic curiosity can be rationalized through a unique symmetry operation that was elucidated by deuteration experiments. In the case of 1,1-diarylalkenes, distal communication between the catalyst and alkene is achieved through subtle alteration of electronic properties and conformation. In this context, a Hammett study lends further credibility to a concerted mechanism. Thus, extended scope exploration, including beta-substitution on the alkene to generate two adjacent stereocenters within the cyclobutane ring, is achieved in a highly stereospecific and enantioselective fashion (33 examples, up to >99:1 er).
