alkynylpyrrolidine 4 was made via a dearomatising cyclisation of an aromatic amide, and was elaborated by stannylcupration and palladium-catalysed coupling to achieve the first total synthesis of three members of the isodomoic acid family; the same alkyne can be envisaged as a precursor to several more of this class of amnesic shellfish toxins.
炔基吡咯烷4是通过芳族酰胺的脱芳构环化制得的,并通过苯乙烯化和钯催化的偶联进行精制,以实现异碘酸家族中三个成员的首次全合成。可以将同一炔烃作为此类失忆性贝类毒素中几种毒素的前体。
