Optically pure N‐Boc‐norpandamarilactonine‐B was diastereoselectively synthesized starting from L‐serine by employing a double ring closing metathesis (RCM) of a tetraene derivative as a key reaction. N‐Boc‐norpandamarilactonine‐B obtained was further converted to pandamarilactonine‐A.

A facile route to naturally occurring (±)-norpandamarilactonines A and B, (±)-pandamarilactonines A-D, and pandanamine has been described from 3-methylfuran-2(5H)-one, with a reductive intramolecular aza-Michael-type addition as the key step.
