The iodination of N-H or N-benzylpyrazoles using elemental iodine in the presence of CAN as the in situ oxidant is a mild and efficient method to prepare 4-iodopyrazoles containing even electron-withdrawing substituents. The reaction is regioselective since the iodine atom preferred pyrazole instead

The Ziegler intermediate 2, previously used in three total syntheses of forskolin (1) has been synthesized efficiently from enone 3. The key transformation of this sequence is the early and stereoselective introduction of the C-6, C-7 oxygen functional groups present in the natural product. The hig

A simple route for the enanrioselective synthesis of key intermediates (11 and 12) for the total synthesis of forskolin has been developed starting from acid 6 and (S)-alcohol 5. The latter is prepared by enantioselective catalytic CBS reduction of dienone 3, and is converted by an intramolecular Di
