A diastereoselective synthesis, using the Yonemitsu-type trimolecular condensation as the key step, has been used for the preparation of 3,4-heterocycle(furanone-, pyrrolidinone- and pyranone-) annulated tetrahydro-beta-carbolines. The chirality Of D-glyceraldehyde or that of the Garner's aldehyde ensured a high and predictable diastereocontrol of the additional newly created stereocentres. (c) 2005 Elsevier Ltd.
