摘要
A concise and highly convergent practical synthesis of topoisomerase 1 inhibitor luotonin B was developed in a one-pot process in excellent yields. The C and D rings of luotonin B was constructed by cascade cyclizations of 2-cyanoquinoline-3-aldehyde or 2-cyanoquinoline-3-hemiacetal with methylanthranilate under acidic conditions. The luotonin B was then converted into luotonin E by an acid-catalyzed etherification reaction.
