Curacin A is a structurally novel antimitotic agent isolated from the Caribbean cyanobacterium Lyngbyamajuscula. Its planar structure has been previously determined from a spectroscopic investigation. Here, we define the complete relative and absolute configuration of curacin A by comparison of products obtained from chemical degradation of the natural product with the same substances prepared by

The absoluteconfiguration of curacin A was determined as (2R,13R,19R,21S)-1 by comparison of degradation products 2 and 3 with the same materials prepared by asymmetricsynthesis. The total synthesis of 1 was completed from (1R,2S)-2-methylcyclopropanecarboxylic acid (8) and the amino alcohol derivative 46. The latter was prepared from 4-pentynal (14) and the Garner aldehyde (43). Asymmetric allylation
