  • Abstract
  • Look Inside

1) β-Phenylethlamine (I), β-p-methoxyphe-nylethylamine (II) and β-3, 4-dimethoxypheny-lethylamine (III) were synthesized by the fol-lowing reaction course :

benzylalcohol—→benzylchloride—→dpenzyl-cyanide—→β-phenylethylamine

2) Chemical behaviors of these substances are affected remarkably with methoxy groups introduced into the phenyl nucleus. Increase of the number of methoxy groups on the phenyl nucleus leads to the increase of basicity of the terminal nitrogen (-NH2) by their electronic effect.

3) The decomposition by monoamine oxidase was studied on these amines, such as I, II, III, and several relating monoamines like ephedrine.

As for the substance I, II and III, the de-gree of the enzymic decomposition decreases with increasing number of methoxy groups as in the order of I>II>III Er. Mescaline, which has one more methoxy group than the sub-stance III, is more difficultly attacked by the enzyme than the latter III. Both benzedrine and ephedrine are not attacked by the enzy-me.
