MDM2 and MDM4 proteins prevent apoptosis of cancer cells by negatively regulating the transcription factor p53. Compounds according to Formula I
are selective antagonists of MDM2 and MDM4 proteins, disrupting the p53/MDM2 and p53/MDM4 complex. These compounds therefore are candidate therapeutics for treating cancer as well as other cell proliferative disease states.

A cooperative chiral guanidine/Ag(I) catalyst system was developed for the asymmetric isocyanoacetate aldol reaction with isatins. The corresponding chiral spirooxindoleoxazolines were obtained in good yields (up to 99%), moderate diastereoselectivities (up to 88:12 dr) and good enantioselectivities (up to 90% ee).

A highly efficient one-step Rh-catalyzed preparation of reduced Knoevenagel adducts of various aldehydes and ketones with active methylene compounds has been developed. The protocol does not require an external hydrogen source and employs carbon monoxide as a deoxygenative agent. The use of malonic acid or cyanoacetamide enabled efficient formal deoxygenative addition of methyl acetate or acetonitrile to aldehydes. The developed methodology was applied to the synthesis of the precursors of biomedically important compounds.
