2-alkenyl-4-quinolones were accessed via a high-yielding, three-step synthesis starting from 2-methyl-4-quinolones using a one-pot phosphorylation-olefination sequence as the key step and SEM as a convenient protecting group. This protocol tolerates various functional groups and gives the target olefins with complete (E)-selectivity.
通过一锅磷酸化-烯化序列作为关键步骤和SEM作为方便的保护基团,从2-甲基-4-喹诺酮类化合物开始,通过高产率的三步合成法从2-甲基-4-喹诺酮类化合物中获得2-链烯基-4-喹诺酮类化合物。该方案可耐受各种官能团,并为目标烯烃提供完全的(E)选择性。
