Three New Amides from Zanthoxylum rubescens.
ZANTHOXYLUM RUBESCENS stem bark has afforded three new unsaturated aromatic amides identified as N-methyl, N-(3,4- methylenedioxyphenylethyl),3',4-dimethoxycinnamoylamide ( 1), N-(3,4-methylenedioxyphenylethyl)-3'-4'-dimethoxycinnamoylamide ( 2), and N-(3,4-dimethoxyphenylethyl), 3',4'-methylenedioxycinnamoylamide ( 3). The structures of these TRANS-cinnamoylamides have been derived on the basis of spectral studies which have been confirmed by synthesis.
