Abstract

Pseudohygrophorones A¹² and B¹² are cyclohexenone derivatives isolated from Hygrophorus abieticola (Basidiomycete) as anti-phytopathogenic compounds. In this study, the first synthesis of (±)-pseudohygrophorones A¹² is reported, utilizing Michael–aldol cascade reaction for constructing the 3,3-dimethyl-2,4-dioxabicyclo[3.1.1]nonan-9-one skeleton and the diastereoselective addition of alkyllithium to the one-side blocked ketone as the key steps.
