Novel soluble polymer supported synthesis of 1,2,3,4-tetrahydro-β-carboline  derivatives in the microwave oven is reported. Commercially available  Fmoc-protected tryptophan was directly anchored to MeO-PEG-OH via  an ester linkage in the presence of DCC and DMAP. One pot cyclocondensation  of polymer-bound tryptophan with a variety of aldehydes and ketones  has been carried out under microwave irradiation to provide immobilized  1,2,3,4-tetra-hydro-β-carboline derivatives. The desired  products were then liberated from the soluble matrix in good yield  and good purity.
