The Intramolecular Diene-Carbene Cycloaddition Equivalence and an Enantioselective Birch Reduction-Alkylation by the Chiral Auxiliary Approach. Total Synthesis of (+/-)- and (-)-Longifolene

Total syntheses of racemic and optically pure (-)-longifolene (1) illustrate (1) a preparation of 6-alkyl-6-(methoxycarbonyl)-2,4-cyclohexadien-1-ones (e.g., 5a) by Birch reduction-alkylation of methyl o-methoxybenzoate and the chiral benzoic acid derivat
