Efficient synthesis of okadaic acid. 1. Convergent assembly of the C15- C38 domain

A convergent synthesis of the C15-C38 domain of the marine natural product okadaic acid is reported. This involved the preparation of intermediates representing the C16-C27 and C28-C38 portions of okadaic acid, their direct coupling, and elaboration to th
