  Asymmetric Total Synthesis of Tacamonine (Pseudovincamone I) via Radical Cyclization

  摘要：

  The radical cyclizations of (+/-)-(E)-3-((2-(bromomethyl)butoxy)carbonyl)prop-2-enoates 11 and 12 and (+/-)-ethyl (E)-3-{N-[2-(bromomethyl)butyl]-N-[2-(3-indolyl)ethyl]carbamoyl} prop-2-enoate (25) were carried out with (TMS)(3)SiH or Bu(3)SnH in the presence of AIBN. (-)-(2S)-2-((tert-Butyldimethylsilyloxy)methyl)butan-1-ol (6), which was prepared by two different methods, was converted into (+)-25. The radical cyclization of(+)-25 produced piperidinone 18 as a diastereomeric mixture, which was transformed into tacamonine (1).

• Synthesis of Six-Membered Compounds by Environmentally Friendly Cyclization Using Indirect Electrolysis

  [Ni(cyclam)](ClO4)(2)-catalyzed indirect electroreduction of olefinic bromides produced six-membered compounds in low to high yields. The synthetic intermediate 49 of Ipecac and Corynanthe alkaloids was obtained in 88% yield in a highly stereoselective manner. Lactam 66, the synthetic precursor of tacamonine, was prepared in 49% yield as a mixture of two diastereoisomers. The electrolysis of the bromoacetates gave the debrominated compounds in good yields.
• Total synthesis of (+)-spiculoic acid A

  The total synthesis of natural (+)-spiculoic acid A, a new cytotoxic marine natural product of polyketide origin, has been accomplished for the first time. The key step of the total synthesis was a stereciselective and high-yielding intramolecular Diels-Alder reaction of a highly functionalized (E,E,E)-2,7,9-dodecanal derivative for the construction of the core tetrahydroindan-2-one skeleton.
