杂环化合物的加成反应。第72部分。与1,2,6,7,8,9-六氢吡咯并[3,2,1- jk ]咔唑的乙炔二羧酸二甲酯
摘要:
1,2,6,7,8,9-六氢吡咯并[3,2,1- jk ]咔唑与乙酰二羧酸二甲酯在乙酸水溶液中反应得到四种复杂的产物,其结构与其13 C nmr及其他光谱有关。将咔唑作为烯胺水解为相应的氨基酮,并检查了后者与炔属酯的反应。结论是乙炔首先攻击5b位置的咔唑,然后开环成氨基酮,然后转化为复杂产物。讨论了环己酮的分子内脱氢成烯胺残基的环己二烯基,该烯胺残基本身转化为相应的胺。

Construction of the highly strained CDEF parent tetracycle, a structural motif found only in the potent ectoparasiticidal agents (+)-nodulisporic acids A and B and related congeners, has been achieved via a new modular indole synthesis, exploiting a sequential Stille cross-coupling/Buchwald-Hartwig union/cyclization tactic. The new indole synthesis holds the promise of rapid assembly of diverse, highly substituted indoles possessing uncommon substitution patterns.
