  A General Synthetic Approach to the (20S)-Camptothecin Family of Antitumor Agents by a Regiocontrolled Cascade Radical Cyclization of Aryl Isonitriles

  摘要：

  A general and efficient synthesis of (20S)-camptothecin (1a) is reported. A key common intermediate containing the pyridone and lactone (DE) rings of camptothecin and most derivatives was constructed from 2-trimethylsilyl-6-methoxypyridine by a series of metalation reactions and a Heck cyclization to provide an achiral bicyclic enol ether. Sharpless asymmetric dihydroxylation followed by lactol oxidation and iododesilylation produced the key intermediate in 94% enantiomeric excess. Alkylation with propargyl bromide and a cascade radical reaction with phenyl isonitrile then produced 1a. About 20 other penta- and hexacyclic analogues of camptothecin with differing single or multiple substituents at C7, C9, C10, C11, and/or C12 were made by changing the propargylating agent and the isonitrile. Included among these are several drug candidates and the approved drugs topotecan and irinotecan. The synthesis of the prodrug irinotecan is direct one that does not pass through the active metabolite. The use of ortho-trimethylsilyl-substituted isonitriles allows the regioselective synthesis of camptothecin analogues in cases where isomeric mixtures are formed from the parent isonitriles. The synthesis of the derivatives relies on the broad scope and functional group tolerance of the key cascade radical reaction.

  irinotecan and SN‐38 were successfully synthesized by a photocatalyzed radical cascade cyclization from an N‐propargyl iodopyridinone and an arylisonitrile under visible light with a ruthenium catalyst. This synthetic method provided a useful entry into composing camptothecin family of antitumor agents in good yields under mild reaction conditions without the use of heavy metal reagents.

• Selective N-functionalization of 6-substituted-2-pyridones

  日期：1995.12

  6-Substituted-2-pyridones can be selectively N-alkylated by treatment with NaH/LiBr in a mixture of DMF and DME. Yields of N-propargylated, N-allylated, and other N-functionalized products are good, and only small amounts of the isomeric O-alkylated product (<10%) are typically formed.
