Studies on the chemical constituents of Rutaceous plants. Part 45. Novel phenyl propanoids: cuspidiol, boninenal, and methyl boninenalate

Abstract

Cuspidiol, boninenal, and methyl boninenalate were established as having the structures 3-{4-[(E)-4-hydroxy-3-methylbut-2-enyloxy]phenyl}propanol (1), (E)-3-{4-[(E)-4-hydroxy-3-methylbut-2-enyloxy]phenyl}propenal (2), and (E)-3-{4-[(E)-4-methoxycarbonyl-3-methylbut-2-enyloxy]phenyl}propenal (3) respectively. The three compounds were also independently synthesized.
