Article abstract of DOI:10.1002/hlca.19860690805

Enantiomerically pure β-necrodol (1) and its 1-epimer 16 have been synthesized starting from aldehyde 5.The two key steps are an asymmetric conjugate addition/Mannich reaction tandem (10->12) and a type-II-magnesiumene cyclization/oxidation sequence (14->1 + 16).
