An efficient procedure for the asymmetric synthesis of 1-substituted1,2,3,4-tetrahydro-9-methyl-beta-carbolines based on asymmetric electrophilic alpha-amidoalkylation reactions is described. Stereoselective addition of various organometallic reagents to a chiral N-acyl-beta-carbolinium ion gave the corresponding 1-substituted 1,2-dihydro-beta-carbolines in high yields and very good to excellent diastereomeric ratios. Catalytic hydrogenation followed by the removal of the chiral auxiliary via reductive cleavage of the amide bond proceeded with complete conservation of the absolute configuration at the newly created stereocenter leading to 1-substituted 1,2,3,4-tetrahydro-9-methyl-beta-carboline derivatives in high yields. Their absolute stereochemistry was proven by X-Ray analysis. The 1-phenyl-substituted 1,2,3,4-tetrahydro-beta-carbolines were evaluated for their affinity to the PCP binding site of the NMDA receptor.

Among the synthesized compounds 2a and 2n showed the best anti-inflammatory activity (inhibition rate: 95% and 92.7%, respectively) and analgesic effect (inhibition rate: 100% and 100%, respectively), which was greater than that or nearly equivalent to that of indomethacin. Compounds 2a and 2n were selected to test their inhibitory effects against ovine COX-1 and COX-2 using the cyclooxygenase inhibition assay in vitro. Compounds 2a and 2n are weak inhibitors of COX-1 isozyme but displayed moderate COX-2 isozyme inhibitory effects (IC50 = 0.47 muM and 1.63 muM, respectively) and COX-2 selectivity indexes (SI = 11.5 and 4.8).
