Cyclo(l-tyrosyl-l-tryptophanyl) dimethylformamide solvate

摘要

The structure of the title compound [systematic name: (3S,6S)-3-(4-hydroxy­benz­yl)-6-(1H-indol-3-ylmeth­yl)piperazine-2,5-dione dimethyl­formamide solvate], C20H19N3O3·C3H7NO, contains hydrogen-bonded tapes typical for diketopiperazines. The structure is stabilized by strong inter­molecular inter­actions of the types O—H⋯O and N—H⋯O involving the dipeptide and the solvent mol­ecules. The absolute configuration was known from the starting materials.
