The synthesis and the spectroscopic data of 14 novel 4-substituted mescaline derivatives are reported. Starting from syringalclehyde (=4-hydroxy-3,5-dimethoxybenzaldehyde). several ethers were obtained from reaction with a series of corresponding saturated and unsaturated alkyl- and fluoroalkyl halides. Henry-reaction with MeNO2 or EtNO2 followed to afford the nitro-olefines, which were then reduced with AlH3 to the desire(d) 2-phenylethyl- and 1-methyl-2-phenylethylamine derivatives.
