2-SUBSTITUTED INDOLES, THEIR PRECURSORS AND NOVEL PROCESSES FOR THE PREPARATION THEREOF
Disclosed are processes for the preparation of 2-substituted indole compounds wherein the 2-substituent comprises an R4 group, wherein R4 is selected from the group consisting of monocyclic aromatic, polycyclic aromatic, monocyclic heteroaromatic, polycyclic heteroaromatic, 1 alkyl, and alkenyl, all of which are optionally substituted at one or more substitutable positions with one or more suitable substituents, and wherein R4 is bonded to the 2-position of the indole ring via a C-C bond; the process comprising reacting an ortho?gem-dihalovinylaniline compound of the formula (I): wherein Halo comprises Br, Cl, or I; each of the one or more R1 is independently selected from the group consisting of H, fluoro, lower alkyl, lower alkenyl, lower alkoxy, aryloxy, lower haloalkyl, lower alkenyl, -C(O)O-lower alkyl, monocyclic or polycyclic aryl or heteroaryl moiety, or R1 is an alkenyl group bonded so to as to form a 4- to 20-membered fused monocycle or polycyclic ring with the indole ring; all of which are optionally substituted with one or more suitable substituents at one or more substitutable positions; R2 comprises H, alkyl, cycloalkyl, aryl, heteroaryl, aryl-loweralkyl-, or heteroaryl-loweralkyl-, all of which are optionally substituted at one or more substitutable positions with one or more suitable substituents; R3 comprises H, alkyl, haloalkyl, alkenyl, alkynyl, aryl, heteroaryl, cycloalkyl, heterocycle, aryl-(C1-6)alkyl-, or heteroaryl-loweralkyl-, all of which are optionally substituted at one or more substitutable positions with one or more suitable substituents; with an organoboron reagent selected from the group consisting of a boronic ester of R4, a boronic acid of R4, a boronic acid anhydride of R4, a trialkylborane of R4 and a 9-BBN derivative of R4; in the presence of a base, a palladium metal pre-catalyst and a ligand under reaction conditions effective to form the 2-substituted indole compound. Also disclosed are processes for the preparation of ortho-gem-dihalovinylaniline compounds. Novel compounds prepared by the processes and novel uses of the compounds are likewise disclosed.
