- 論文の詳細を見る
Two kinds of reactions were carried out on the components of the seeds of Hernandia ovigera L. The reaction of lead tetraacetate on desoxypodophyllotoxin (I) and its analogous compounds caused the cleavage of methylenedioxyl group, affording the corresponding diphenols. In the case of 3,4-methylenedioxypropylbenzene (XII), an intermediate acetoxyl compound (XIII) was isolated. The reactions of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) on I and its analogous compounds afforded smoothly aromatized compounds. By the same reaction on bursehernin (III), cyclization and aromatization occurred simultaneously affording chinensin (XVIII) which was confirmed by direct comparison with authentic speciemen. The results of the cleavage reaction on I and XII by use of borontrichloride were also described.
