Abstract
A regioselective biomimetic synthesis of bioactive natural products dunnione and nor-β-lapachone is described. This cascade provides a new strategy of a one-pot process mediated by Lewis acid NbCl5 involving a tandem Claisen rearrangement–cyclization reaction. This procedure was efficient, mild, and easily scalable that avoided using highly hazardous concd H2SO4.
