It can be isolated only in very small quantities from some plant species. This paper describes the first reported laboratory synthesis of nepetoidin B.
Technical Abstract: The total synthesis of nepetoidin B (the 2-(3,4-dihydroxyphenyl)ethenyl ester of 3-(3,4-dihydroxy¬phenyl)-2-propenoic acid) has been achieved in two steps from commercially available 1,5-bis(3,4-dimethoxyphenyl)-1,4-pentadien-3-one. Tetramethylated nepetoidin B was prepared directly by Baeyer-Villiger reaction with oxone; its demethylation with boron tribromide afforded nepetoidin B.
