    Studies on the synthesis of mavacurine-type indole alkaloids. First total synthesis of (±)-2,7-dihydropleiocarpamine
    摘要:
    Closure of the six-membered C ring of pentacyclic mavacurine-type alkaloids from suitably substituted tetracyclic substructures embodying rings ABDE of these alkaloids, either by electrophilic cyclization upon the indole 3-position or by intramolecular alkylation of the piperidine nitrogen, failed. In contrast, 6a-homopleiocarpamine (45) has been synthesized from dithioacetal 42 by an electrophilic cyclization involving the closure of the seven-membered C ring. The first total synthesis of the alkaloid 2,7-dihydropleiocarpamine (68) has been achieved by photocyclization of the tetracyclic chloroacetamide 54 as the key step. The required tetracyclic ABDE ring systems were prepared by a straightforward sequence consisting of nucleophilic addition of a 1-indoleacetatic ester enolate to the gamma position of a pyridinium salt, acid cyclization of the resulting 1,4-dihydropyridine, and final elaboration of the (E)-ethylidene substituent. An alternative synthesis of the tetracyclic alkaloid vinoxine (10a) is also reported.

    4-Dihydropyridines 3 resulting from the addition of the enolate derived from 1-acetylindole (1) to pyridinium salts 2 do not undergo cyclization under the usual acidic conditions, but do satisfactorily cyclize to the tetracyclic derivatives 4 by treatment with TsOH in the presence of lithium iodide.
    由1-乙酰基吲哚(1)衍生的烯醇化物加到吡啶鎓盐2中而得到的1,4-二氢吡啶3在通常的酸性条件下不进行环化,但通过在TsOH中进行TsOH处理,可以令人满意地环化为四环衍生物4。的存在。
