Total synthesis1 of modified ellipticines and is described from 2-chloronicotinic acid and respectively 5-methoxy -indole and 5-azaindole in 11 to 13 steps with overall yields of 11% and 18%. With respect to the numerous synthesis described in the litterature, the originality of this approach resides above all in the formation of ring C in basic medium, such conditions being dictated by the presence
全合成1改性ellipticines的和从2-氯烟酸描述并分别5-甲氧基-吲哚并在11至13个步骤为11%和18%的总产率5-氮杂吲哚。关于文献中描述的大量合成,该方法的独创性首先在于在碱性介质中环C的形成,在α2的情况下,这种条件由吡啶A环的存在所决定。两种合成方法均已推断出可产生数公斤的最终产物。第二部分涉及前体1的四环结构的修饰。
