  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).
