摘要

Four simple 0-disubstituted aromatic amines have been isolated from the leaves of Justicia gendarussa Burm and characterized as 2-amino benzyl alcohol (3), 2-(2′-amino- benzylamino) benzyl alcohol (4) and their respective 0-methyl ethers 1 and 2 from 1H NMR and mass spectral analyses of the bases and their acetates. Structures 3 and 4 have also been confirmed by synthesis. Intramolecular hydrogen bonding (cf. 9, 13 and 14) has ...
