Asymmetric nucleophilic catalysis with planar-chiral DMAP derivatives and chiral phosphines : synthetic and mechanistic studies
… that furnish an array of diastereomerically pure bicyclic compounds bearing two or three contiguous tertiary! quaternary stereocenters.

Asymmetric Dihydroxylation and Aziridination of Allenes and Related Chemistry
… established. Efficient ring opening of these bicyclic compounds may provide synthetic utility in organic chemistry. The intramolecular aziridination of allenic sulfamate esters was tested on a single example to afford in situ a ring opened product.

Carbenoid insertions and cyclometallations of zirconacycles
… n2-alkene complex, to generated bicyclic compounds, was investigated.

Organomanganese compounds in organic synthesis
… transformation of enynes to cyclopropanated bicyclic compounds and cyclopentanes bearing an exocyclic double bond. In the current study, benzylmanganese pentacarbonyl was used instead of methylmanganese pentacarbonyl under similar conditions. In the current study however, the type of product …

Synthetic Studies Of Biologically Active Molecules: Irl 2500, Bruceantin, And Biliatresone
… Pauson Khand reaction utilizing a strained bicyclic compound to generate bridged cyclohexenones via a [3+2+1] cycloaddition as a possible method to generate the bruceantin ring system. The synthesis of suitable bicyclic substrates for this reaction has been achieved, and their viability in a …

Tandem reaction sequences on a zirconocene template
… method for a rapid construction of novel bicyclic compounds with the potential for functionalization at multiple sites. Such obtained analogues provided an attractive template for structure-activity studies with respect to investigating the biological function of the human orphan nuclear …

NMR response of liquids and of natural gas mixtures
… from alkane correlations, it is found that bicyclic compounds and base oils do not. Another situation this work addresses is the determination of T 1 and T 2 for gaseous mixtures of methane and other natural gas components. The measurements illustrate the effect of density and composition on …

The synthesis and reactions of thienopyridines
… identical conditions, however, does not give the bicyclic compounds but ketene dithioacetals (I, J and K). Increasing the reaction temperature allows formation of thienopyridines (E, G and H; R, R<sub>1</sub> = CN; X = NHPh). Thienopyridines R = CO<sub>2</sub>Et; R<sub>1</sub> = CO<sub>2</sub>Me, …

Design, Synthesis, and Evaluation of Covalent CADA Analogues as Potent TLR4 Downmodulator for the Treatment of Opioid Use Disorder
… allows for the formation of medicinally valuable bicyclic compounds via pendant nucleophiles. In this work, we applied previously reported oxidative photocatalytic conditions by the Yoon group to cyclize novel substrates containing N-tosyl amines into medicinally relevant bicyclic scaffolds. Proof …
