using a Pd(OAc)2/PCy3 system is described. A wide range of 2-arylbenzoyl fluoride derivatives can be used as fluorenone precursors and the reaction proceeds via an intramolecular coupling between aromatic C–H bonds with acyl C–F bonds. The reaction can be applied to the synthesis of indenofluorenedione derivatives and to the construction of other molecules with five-membered rings.

The formation of exo‐methylene indanones and indenones from simple ortho‐allyl benzoic acid derivatives has been developed. Selective formation of the indanone or indenone products in these reactions is controlled by choice of ancillary ligand. This new process has a low environmental footprint as the products are formed in high yields using low catalyst loadings, while the only stoichiometric chemical
The present invention provides non-peptide compounds that mimic the streptococcal SspB Adherence Region (BAR) and function as inhibitors of P. gingivalis adherence to streptococci. The invention also provides methods of making and using the inhibitors.
The present invention relates to novel compounds which make it possible to transfer nucleic acids into cells. These novel compounds are lipid derivatives of polythiourea. They are useful for the in vitro, ex vivo or in vivo transfection of nucleic acids into various cell types.

are defined herein. These compounds are useful in the prevention and treatment of infection by HIV and in the prevention, delay in the onset, and treatment of ASS. The compounds-are employed against HIV infection and AIDS as compounds per se or in the form of pharmaceutically acceptable salts. The compounds and their salts can be employed as ingredients in pharmaceutical compositions, optionally in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of preventing, treating or delaying the onset of AIDS and methods of preventing or treating infection by HIV are also described.
