Parallel synthesis of beta-carbolines on soluble polyethylene glycol (PEG-OH) support is demonstrated. One-pot condensation of polymer-bound tryptophan residues with various aldehydes and ketones has been carried out in the presence of p-TSA as a catalyst to deliver immobilized 1,2,3,4-tetrahydro-beta-carbolines. Subsequent disengagement of the appendant from the polymer support afforded the desired products in good yield and acceptable purity. (C) 2003 Elsevier Science Ltd. All rights reserved.
