The present invention provides novel compounds of formula (I) and pharmaceutical compositions containing these compounds. The compounds of formula (I) can act as CXCR4 modulators that specifically target the CXCR4 minor pocket, and they have further been found to inhibit the production of inflammatory cytokines in immune cells, which renders these compounds highly advantageous for use in therapy, particularly in the treatment or prevention of an inflammatory disorder, an autoimmune disorder, an autoinflammatory disorder, or an interferonopathy, such as, e.g., lupus erythematosus, dermatomyositis or rheumatoid arthritis.

Sodium and potassium enolates of 1,3-diacylimidazolidin-2-ones undergo clean alkylationreactions with reactive alkylhalides; the latter enolates reacting generally more stereoselectively due, it is proposed, to the lower temperature at which the reactions proceed. The reactions are all stereoregular, with the diastereoisomeric identity of products being established unambiguously by the synthesis
The expedient synthesis of a novel chiral (1S,2S)-N-[(2-isothiocyanato)cyclohexyl] trifluoromethanesulfonamide and its use as a derivatizing auxiliary for the straightforward determination of optical purity of chiral amines are reported.
An enantioselective borane-mediated deacylation of C2-symmetrical 1,3-diacetyl-2-imidazolidinethiones, catalyzed by oxazaborolidines derived in situ from an aminoalcohol 2 and borane, provides a promising process for highly effective kinetic resolution.
