摘要：

A family of kolovane and norkolovane diterpenoids 6-14 has been isolated from leaves of the tropical tree Casearia corymbosa. These structures have been assigned based on data provided by various spectroscopic techniques, including a variety of 2D nmr experiments. Each of these nine compounds contains an unusual, highly oxidized C ring that may be viewed as a protected dialdehyde; the norkolovanes contain an additional aldehyde group as well.
