Abstract
The facile synthesis of tetracyclic molecular frameworks employing
a Lewis acid promoted domino reaction of naphthoquinones with hydroxy-
and amino-functionalized cross-conjugated trienes is reported. The
reaction cascade involves a heterocyclization via hemiacetal or
imine formation, and an intramolecular Diels-Alder
cycloaddition.
Key words
tetracyclic scaffolds - naphthoquinone - Lewis
acid promoted domino reaction - intramolecular Diels-Alder
cycloaddition

The reactions were monitored by LC-MS
and TLC on silica gel.

The structures and relative stereochemistries
were unambiguously assigned by 1D and 2D NMR experiments (including
NOESY). Full characterization of the novel skeletons with their
NMR data and spectra are included in the Supporting Information.
