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 46 presumably involves a transient nitrone 5 which undergoes a highly regioselective intramolecular addition to a non-polarized olefinic bond.
