title: New tetracyclic tetrahydro-beta-carbolines as tryptophan-derived peptidomimetics.
abstract: The Pictet-Spengler reaction is known as a useful tool for the synthesis of constrained analogs of tryptophan. Herein, we present the further cyclization of 1,2,3,4-tetrahydro-beta-carboline-3-carboxylic acid methyl esters with 1-(1'-aminoalkyl) side chain. These transformations lead to heterocyclic structures which can find useful applications in medicinal chemistry as peptide mimetics.
