Synthesis of Marine Sponge Bisindole Alkaloids Dihydrohamacanthins

Organic Letters, 2002
[structure: see text] A convergent synthesis of the marine sponge bisindole alkaloids dihydrohamacanthins is described. The synthesis centers on the construction of 3,5- and 3,6-linked pyrazinones and their reduction to the requisite piperazinones with sodium cyanoborohydride.

Synthesis of a novel series of cytotoxic bisindole alkaloids

Bioorganic & Medicinal Chemistry Letters, 2001
Original cytotoxic bisindole alkaloids with a 1,2,3,4-tetrahydroquinoline bridge were synthesized by reductive amination with various anilines. The most cytotoxic compounds display a high and dose-dependent cell cycle effect with accumulation in the G1 phase.

Alternative partial synthesis of bisindole alkaloids

Tetrahedron Letters, 1990
Abstract Indoline derivatives of the pericyclivine series are oxidized at position 6 with DDQ; the corresponding alcohols are coupled with nucleophilic indolines under acid conditions to yield dimers similar to undulatine.

Leucophyllinines A and B, bisindole alkaloids from Leuconotis eugeniifolia

Journal of Natural Medicines, 2019
Two new bisindole alkaloids, leucophyllinines A (1) and B (2) consisting of eburnane and quebrachamine-type skeletons were isolated from the bark of Leuconotis eugeniifolia, and their structures were elucidated on the basis of spectroscopic data. Leucophyllinines A and B showed antiplasmodial activities against Plasmodium falciparum 3D7.

Bisindole alkaloids.

The Alkaloids. Chemistry and biology, 2007
This chapter provides an overview on bisindole alkaloids. The indole–indole and tryptamine–tryptamine type, and related alkaloids are discussed. Tryptamine–tryptamine type with an additional monoterpene unit and related alkaloids are briefly discussed.

Bisindole alkaloid artifacts from Gonioma malagasy

Tetrahedron Letters, 2013
Abstract Three new bisindole alkaloids ( 1 – 3 ), possessing a rare carbon skeleton formed by two indole moieties fused via a dihydropyran unit, were isolated from the alkaloid extract of the stem bark of Gonioma malagasy . Their structure and absolute configuration were assigned thanks to a combination of one and two dimensional NMR spectroscopy ...
