Abstract
Two N-benzylated analogues of the antioxidant, radical scavenging,
and neuroprotective alkaloid neoechinulin A were prepared. Since,
according to SAR studies, stereochemistry does not play an important
role, both analogues were prepared in racemic form, using enaminone
chemistry.
Key words
N-benzylated alkaloid analogues - neoechinulin A - diketopiperazines - enaminones
- 2-isoprenylated - 2-prenylated indoles
References and Notes <A NAME="RD03410ST-1">1 </A>
The term isoneoechinulin A is proposed
by authors of this work and refers to the prenyl group replacing
the isoprenyl group in neoechinulin A. This nomenclature is used
for naming compound 2 .

A crystal structure of isoprenylated
analogue 1 was established from monocrystal,
but the diffraction data were poor for the isoprenylated region
of the molecule; although the X-ray structure obtained unambiguously
showed a Z orientation around the exocyclic
double bond.
