β¦ Synopsis
The pseudoguaianolides constitute a major family of sesquiterpenes, over thirty having been recorded to date. (1) They also afford a singular synthetic challenge in that most members (I) have six asymmetric centers, all grouped on a cycloheptane ring, with both cis-and trans-lactones being represented and C-5 and C-7 bearing identical configurations throughout the
