摘要：

(Chemical Equation Presented) A facile access to optically active 2-indolyl-1-nitro derivatives, which can be easily transformed into highly valuable compounds such as tryptamines and 1,2,3,4-tetrahydro-β-carbolines, is provided by the first catalytic enantioselective Friedel-Crafts alkylation of indoles with nitroalkenes (see scheme; e.g. R1 = R2 = H, R3 = Ph). © 2005 Wiley-VCH Verlag GmbH & Co.
