The synthesis of nitrogen containing ring systems has been one of the interests of this
research group at the University of the Witwatersrand for a long time. These systems form …

Novel Products from Bischler-Napieralski Reaction of Arylacetyl-Tryptophan Esters. Synthesis of
Spiropentacyclic Indolines Struc Page 1 SYNTHETIC COMMUNICATIONS, 23(3), 379-388 (1993) …

Monoterpenoid indole alkaloids are the major class of tryptamine‐derived alkaloids found in
nature. Together with their structural complexity, this has attracted great interest from …

Biosynthetic pathways can be hijacked to yield novel compounds by introduction of novel
starting materials. Here we have altered tryptamine, which serves as the starting substrate …

Abstract The hexahydropyrrolo [2, 3-b] indole alkaloids represent a diverse family of
structurally complex tryptamine derived alkaloids isolated from a widespread series of …

The condensation of glutaraldehyde with (—)-phenylglycinol in the pres-ence of KCN led to
the formation of a single chiral 2-cyano-6-oxazolopiperidine synthon equivalent of 1, 4 …

A unified strategy for the synthesis of congeners of the prenylated indole alkaloids is
presented. This strategy has yielded the first synthesis of the natural product (−)-17-hydroxy …

Almost one hundred benzo [c] phenanthridine alkaloids (refs. 1, 2) have so far been isolated
and they are classified into two groups:(a) fully aromatized and (b) B/C-hexahydro alkaloids …
