Abstract

The title compound, C(33)H(29)N(3)O(5), was synthesized by the reaction of racemic trans-2-benzyl-3-(2-furyl)-1-oxo-1,2,3,4-tetrahydroisoquinoline-4-carboxylic acid, l-tryptophan methyl ester and diisopropylcarbodiimide in dry dichloromethane. The furan ring is disordered over two positions in a 0.859 (14):0.141 (14) ratio. In the 1,2,3,4-tetrahydroisoquinoline ring system, the heterocyclic ring is not planar, with puckering parameters Q(T) = 0.448 (2) angstrom, theta = 64.9 (3) and phi = 268.3 (3)degrees. The crystal is extended into a three-dimensional supramolecular architecture through intermolecular N-H center dot center dot center dot O hydrogen bonds and C-H center dot center dot center dot pi interactions. The absolute structure was assigned by reference to the chiral starting material.
