Abstract
Naturally occurring diarylnonanoids, malabaricones A, B, C, D, and 1-(2-hydroxy-6-methoxyphenyl)-9-(3, 4-methylenedioxyphenyl)-nonan-1-one were synthesized from a common intermediate, 6-benzyloxyhexyltriphenyl phosphonium bromide, by use of the Witting reaction and crossed aldol reaction as key steps.
