A novel one-pot synthesis of tetrahydro-beta-carboline systems via tandem hydroformylation-Pictet-Spengler reaction starting from olefins and aryl ethylamines is described. This tandem procedure allows fast and convenient synthesis of various substituted tetrahydro-beta-carbolines.

Whilst cis:trans selectivity of about 4:1 can be obtained from Pictet-Spengler reactions between tryptophan methyl esters and aldehydes using conditions of kinetic control, much higher cis selectivity (>95:5) can be obtained when both the tryptophan derivative and the aldehyde possess a Suitable pi-system: preliminary results oil the scope and limitations of this exceptional stereocontrol are presented in this Letter.

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.
