(S)-Methyl 2-[(3R,4R)-2-benzyl-3-(2-fur-yl)-1-oxo-1,2,3,4-tetra-hydro-isoquinoline-4-carboxamido]-3-(1H-indol-3-yl)propanoate.


ABSTRACT: The title compound, C(33)H(29)N(3)O(5), was synthesized by the reaction of racemic trans-2-benzyl-3-(2-fur-yl)-1-oxo-1,2,3,4-tetra-hydro-isoquinoline-4-carboxylic acid, l-tryptophan methyl ester and diisopropylcarbodiimide in dry dichloro-methane. The furan ring is disordered over two positions in a 0.859?(14):0.141?(14) ratio. In the 1,2,3,4-tetra-hydro-iso-quin-oline ring system, the heterocyclic ring is not planar, with puckering parameters Q(T) = 0.448?(2)?Å, ? = 64.9?(3) and ? = 268.3?(3)°. The crystal is extended into a three-dimensional supra-molecular architecture through inter-molecular N-H?O hydrogen bonds and C-H?? inter-actions. The absolute structure was assigned by reference to the chiral starting material.
