Tangutorine (1) in the racemic form has been assembled from tryptamine and aldehyde 3.
The synthetic design was based on uncovering a hidden symmetry in the nontryptamine …

We have developed a general one-pot method to provide highly functionalized tryptamine
derivatives, via a Fischer indole type pathway. In this article, we demonstrate optimal …

The reaction of (L)-tryptophan methyl ester with methyl 4-oxobutanoate under conditions of
kinetic control gave a high yield of the cis-1, 3-disubstituted tetrahydro-β-carboline (6); a …

Hyrtioseragamines A (67) and B (68) are heteroatom-rich alkaloids isolated from extracts of
Hyrtios sp. marine sponge that possess a novel furo [2, 3-b] pyrazine-2 (1H)-one core (red) …

Substituted tryptamines, an important class of heterocycle in both natural products and
medicinal chemistry, are readily accessible through a Larock indolization approach. The …

Of various methods available 1, the decarboxylation of tryptophan (1) is the simplest way to
the synthesis of tryptamine (3) which is a very important starting material in the synthesis of …

A diastereoselective synthesis of the unnatural (+)-enantiomer of the
hexahydropyrroloindole alkaloid (-)-pseudophrynaminol (3), isolated from the skin of the …

The novel pyrrole/imidazole alkaloids solsodomine A 1 and B 2 have been isolated from
fresh berries of Solanum sodomaeum L., collected from the Libyan desert. 1 This is the first …
