K. Kaljuste et A. Unden, SOLID-PHASE SYNTHESIS OF 1,2,3,4-TETRAHYDRO-BETA-CARBOLINES - IMPLICATIONS FOR COMBINATORIAL CHEMISTRY, Tetrahedron letters, 36(50), 1995, pp. 9211-9214
A general method for the solid phase synthesis of tetrahydro-P-carboli
nes is described Resin bound tryptophan residues or non-peptide struct
ures carrying 3-(2-aminoethyl)indole structures react rapidly under mi
ld reaction conditions and in high yields with aldehydes to produce C-
l substituted 1,2,3,4-tetrahydro-beta-carbolines in a Pictet-Spengler
reaction The method can be employed to readily produce a wide range of
tetrahydro-beta-carbolines in combinatorial chemistry.
