✦ Synopsis

Stereochemical Issues Related to the Synthesis of 7,10- 10,16,3':3,4]pyrazino[1,2-b]βcarboline-5,8-diones.

-The condensation of iminoethers like (III) with anthranilic acid proceeds with inversion of the tryptophan stereocenter C-16a. Epimerization of the tryptophan center also occurs by acylation with o-azidobenzoyl chloride. -(MADRIGAL, A.;
