A six-step synthesis of rhopaloic acid A (1E) was accomplished in 25% overall yield using the Pd(II)mediated cyclization and methoxycarbonylation of allenyl alcohol 3, which affords 83% of a 6:1 mixture of tetrahydropyranylacrylates 2 and 8, as the key step.

Asymmetric Synthesis of Rhopaloic Acid A Analogues and Their Biological Properties. -In order to study structure-activity relationships of cytotoxic rhopaloic acid, related analogues such as (X) are synthesized. The routes are based on asymmetric alkylation of a chiral oxazolidine (I) and construct
