✦ Synopsis

The common indolizidine core leading to the allopumiliotoxins was synthesized using an intramolecular (Z)-N-4-alkenylnitrone cycloaddition reaction as the key step. The synthesis began with (R)-tert-butyl-3-hydroxypent-4-enoate which was obtained via enzymatic resolution using Amano PS lipase.

A stereoselective synthesis of the decahydrofluorene core of the hirsutellones was accomplished in eight steps and in 43% overall yield. The key step of the synthesis is the highly stereoselective intramolecular Diels-Alder cyclization of the siloxacyclopentene-constrained tetraene 1.
