Substituent Diversity-Directed Synthesis of Indole Derivatives.

J Comb Chem. 2009 May 26; Wang DM, Sun MN, Liu GThis paper reports a versatile, good-yielding, solution-phase method that is a substituent diversity-directed synthesis of 1H-indoles (6-13, 17-20) and 1-hydroxyindoles (14, 15) starting from commercially available 1,5-difluoro-2,4-dinitrobenzene. The synthetic products possessed the maximum six diversity points.
