cryptopleurine (8) and antofine (9) via directed ortho metallation of the common phenanthrene (1) are described (Scheme 2). The utility of this strategy as a new N-heteroring annelation method (Scheme 1) is illustrated by the preparation of other aromatic ring-fused quinolizidine (12,15) and indolizidine (18,21) systems. A Mg for Li transmetallation, crucial for the synthesis of 13 and of potential broader
描述了通过普通菲(1)的定向邻位金属化反应合成菲咯啉-喹唑烷和-吲哚唑烷生物碱,隐藻碱(8)和antofine(9)(方案2)。此策略为新的N-杂环成环方法(所述的实用方案1)由其他芳族环稠合的喹嗪啶(制备图示12,15)和吲哚里(18,21)的系统。报道了一种用于Li过渡金属化的Mg,它对于13的合成至关重要,并且在定向金属化化学中具有潜在的更广泛的意义。
