The naturally occurring Lycopodium alkaloid (+)-luciduline ( 1) has been synthesized from ( R)-5-methyl-cyclohex-2-en-1-one ( 12) by a sequence of seven steps (s. Scheme 6) in 33% overall yield. The key step 4→6 presumably involves a transient nitrone 5 which undergoes a highly regioselective intramolecular addition to a non-polarized olefinic bond.
