Ergot alkaloid, (±)-6,7-secoagroclavine was synthesized from 2-methyl-5-nitroisoquinolinium iodide by three routes. In the course of the study, a novel intra-molecular γ-alkylation of allyl alcohol was found. Reaction of Grignard reagents with nitroalkanes to afford N-alkyl hydroxylamines was effectively used in the present synthesis.
