Abstract

Abstract The palladium catalyzed cross-coupling reaction of indolylborates with various N- protecting groups was investigated, where N-Methyl, N-methoxy, and N-tert-butoxycarbonyl groups were found to be useful. However, triethyl (1-methoxymethylindol-2-yl) borate could not be used for this reaction. It was also found that the alkyl migration reaction of trialkyl (1- methoxymethylindol-2-yl) borate produced 2-alkyl-1-methyl-indole accompanied by the ...
