WebA practical total synthesis of the natural products (+)-isogalbulin and (+)-galbulin has been achieved in 10 steps from readily available 3-(3,4-dimethoxyphenyl)propanoic acid. The total yields were 12.3% and 12.9%, respectively. The key steps involved Evans asymmetric alkylation, Sharpless asymmetric epoxidation, and a highly regioselective opening of 1 … WebArylnaphthalene, also known as 2,7′-cyclolignan, is a subtype of classical lignans. The molecular backbone of arylnaphthalenes is formed through an oxidative dimerization of two phenylpropanoids (C6–C3) units through 8–8′ (β–β′) and 2–7′ connections (Fig. 1).Usually, arylnaphthalenes have been found in many plants in the form of glycosides and aglycones.
