pyrrolo[1,4]benzodiazepine 2 (R = ME), a key intermediate in the synthesis of anthramycin (1), has been prepared via a new approach involving two sequential directed ortho metalation reactions (4) and a previously unreported isatoic anhydride construction (8 → 9).
吡咯并[1,4]苯并二氮杂卓2(R = ME),是蒽霉素(1)合成中的关键中间体,它是通过一种新方法制备的,该方法涉及两个顺序的定向邻位金属化反应(4)和以前未报道的等渗酸酐。结构(8→9)。
