A vinylogous urethane approach towards the synthesis of okadaic acid. Construction of the C1-C8 fragment. Part I
摘要:
A vinylogous urethane approach is utilized to synthesize the C1-C8 fragment of okadaic acid. The key steps include an asymmetric alkylation, a hydroxyl directed iodocarbonate cyclization and a stereoselective cyanohydrin formation. (C) 1998 Elsevier Science Ltd. All rights reserved.

A concise and enantioselective total synthesis of the Veratrum alkaloid cyclopamine is disclosed. This highly convergent synthesis with a 16-step longest linear sequence (LLS) was enabled by a de novo synthesis of the trans-6,5-heterobicycle via a strain-inducing halocyclization process, a key Tsuji–Trost cyclization to construct the fully substituted, spirocyclic THF motif with exquisite diastereocontrol
