hm... kind of, but only if you look only at the side chain.
but look at the whole indole ring system and you will see
that tryptamines (alpha-methyl or not) are indeed cyclicized
and aromated phenetylamines. the amphetamine analog would have
a methyl in the 2-position. (that's probably the reason for
the 2-Me derivates in THIKAL)
