Structural analogues of tadalafil that contain two diversity points have been synthesized from a soluble polymer support employing a Pictet–Spengler reaction using focussed microwave irradiation. Polymer-bound deprotected tryptophan reacts with various aldehydes to generate the tetrahydro-β-carbolines on the support. Subsequently immobilized tetrahydro-β-carboline underwent a highly efficient intramolecular N-heterocyclization in a traceless fashion from various in-situ generated α-alkyl and heteroalkyl amides in two steps to generate tetracyclic 2,5-diketopiperazines in high purity. All the compounds were isolated as cis and trans isomers with good yields.
