Products from furans. XV . Synthesis of novel tyramine derivatives via 6‐hydroxy‐2 H ‐pyran‐3(6 H )‐ones

Furan chemistry was utilized for the synthesis of several novel tyramine derivatives. Thus 2 H ‐pyran‐3(6 H )‐ones were used as keystone intermediates for the preparation of novel α,β‐disubstituted tyramine derivatives. Furthermore by the same approach tyramine was derivatized with a molecule of GABA.
