摘要:
                                A new synthetic entry to the FR901483 core is described. The Pd-mediated cyclization of amino-tethered vinyl halides and ketone enolates from the azaspiro[4.5]decan-8-ones 5 and 10 gives the functionalized 7,10a-methanoperhydropyrrolo[1,2-a]-azocines I and II, respectively.
