| Abstract: | Abstract The title compound 1 has been prepared from the condensation product of a silyl protected amino-oxazoline lactam (3) and Cbz-protected l-tryptophan (4) after hydrogenolysis of the carboxybenzyl protection group. The synthesis and crystal structure of 1 is described. The compound crystallized from DMSO in the monoclinic system, P21 space group with unit cell parameters a = 9.4029(25), b = 6.2828(12), c = 20.681(45), and β = 96.505(16), Z = 2 and a cell volume of V = 1213.9(2) ?3. In the crystal lattice, 1 forms an extensive hydrogen bonded framework consisting of interconnected dimeric chains. |
