✦ Synopsis

ARIGONI, Barton, Corey, Jeger, and collaborators established the complete structure I for limonin. They also proposed the formula II as the plausible and biogenetically attractive one for obacunone. 2 Kubota, Kamikawa, Tokoroyama, and Matsuura proposed the partial structure III on the basis of the degradation reaction of obacunone. 1,3-6 Recently, the partial structure
