  邻氨基苯甲酸 、 (2S,8S)-7-ethoxy-2-methyl-3,6,17-triazatetracyclo[8.7.0.03,8.011,16]heptadeca-1(10),6,11,13,15-pentaen-4-one 反应 2.0h， 以40%的产率得到(1R,15S)-15-methyl-3,11,14,17-tetrazahexacyclo[12.11.0.02,11.04,9.016,24.018,23]pentacosa-2,4,6,8,16(24),18,20,22-octaene-10,13-dione

  Stereochemical issues related to the synthesis of 7,10-dimethyl-7,10,16,16a-tetrahydro-11H-quinazolino[2′,3′:3,4]pyrazino[1,2-b]β-carboline-5,8-diones

  摘要：

  Condensation reactions between anthranilic acid and iminoethers derived from 2,3,6,7,12,12a-hexahydropyrazino[1,2-b]beta-carboline-1,4-diones 3-8 to give the title hexacyclic compounds were studied from a stereochemical point of view. The configuration was retained in the formation of iminoethers, but inversion of the tryptophan sterocenter C-16a took place in the condensation process. Epimerization also occurred in an alternative procedure that involves acylation at N-2 with o-azidobenzoyl chloride, followed by intramolecular aza-Wittig reaction.
