- Site-Specific Alkene Hydromethylation via Protonolysis of Titanacyclobutanes
-
Methyl groups are ubiquitous in biologically active molecules. Thus, new tactics to introduce this alkyl fragment into polyfunctional structures are of significant interest. With this goal in mind, a direct method for the Markovnikov hydromethylation of alkenes is reported. This method exploits the degenerate metathesis reaction between the titanium methylidene unveiled from Cp2Ti(μ-Cl)(μ-CH2)AlMe2 (Tebbe's reagent) and unactivated alkenes. Protonolysis of the resulting titanacyclobutanes in situ effects hydromethylation in a chemo-, regio-, and site-selective manner. The broad utility of this method is demonstrated across a series of mono- and di-substituted alkenes containing pendant alcohols, ethers, amides, carbamates, and basic amines.

- Synthesis of functionalized 2-isoxazolines as three-dimensional fragments for fragment-based drug discovery
-
Abstract The design of new sp3 and spiro-enriched fragments has been achieved from 1,3-dipolar cycloaddition between alkenes and chloro-oximes. The selection of reagents was performed to afford a panel of 2-isoxazoline-containing fragments that show desirable three dimensional (3D) characteristics to allow the probing of biologically-relevant chemical space. Principal moments of inertia (PMI) were calculated to evaluate the 3D diversity. The resulting 3D fragments with suitable physicochemical properties, especially a good solubility, will be used to improve the hit rate of our fragment-based screening.
