  Synthesis of Homofascaplysin C and Indolo[2,3-a]carbazole from Ditryptophans

  摘要：

  The 2,2'-biindole core of ditryptophan cross-links is prominent in the fascaplysins and the indolocarbazole glycoside natural products. N-Acyliminium ions derived from the C-terminus of ditryptophan peptides cyclize in one of two modes: N-alkylation or C-alkylation. The surrounding peptide offers some control over the course of the cyclization and allows the preparation of homofascaplysin C or indolo[2,3-alpha]carbazole. These targets are modest, but they are generated through carbocyclic intermediates rich in stereochemistry, and decidedly non-peptide in character.
