Chemodivergent reactions of 2,2-dimethoxyacetaldehyde and anilines were described, which were established on the basis of either a CC bond cleavage or a rearrangement process of a reaction intermediate. These reactions proceeded in a condition-determined manner with good functional group tolerance. In the first model, 2,2-dimethoxyacetaldehyde reacted with aniline to form a new CN bond, in the presence

A new approach is described for the synthesis of substi- tuted indoles 5, through an intramolecular and regioselective Friedel-Crafts cyclization of enaminones 6a-h catalyzed by Lewis acids. Compounds 6 were prepared from the 2-anilinocarbonyl compounds 7, by treatment with DMFDMA under thermal or mi- crowave (MW) irradiation conditions. An alternative and shorter one-pot two-step synthesis of indoles
The present invention is directed to compounds which inhibit farnesyl-protein transferase (FTase) and the farnesylation of the oncogene protein Ras. The invention is further directed to chemotherapeutic compositions containing the compounds of this invention and methods for inhibiting farnesyl-protein transferase and the farnesylation of the oncogene protein Ras.

An unprecedented radical cross‐coupling reaction was achieved between glycine esters and racemic α‐bromoketones catalyzed by synergistic Brønsted acid/photoredox catalysis, thus serving as an efficient platform for the synthesis of highly valuable enantioenriched unnatural α‐aminoacid derivatives. This dual catalysis provides a powerful capability to control the reactive radical intermediate and iminium
