By taking advantage of our novel synthetic methods involving CsF-mediated Claisen rearrangement of an aryl propargyl ether to a 2-methylbenzolfuran and oxidative cleavage of the furan ring to a salicylaldehyde, total synthesis of chelerythrine, a benzo[c]phenanthridine alkaloid, was accomplished via the common intermediate (5) prepared through the two routes shown in Chart 3.
利用我们的新颖合成方法,包括CsF介导的芳基炔丙基醚克莱森重排为2-甲基苯并呋喃以及呋喃环氧化裂解为水杨醛,完成了苯并[c]菲啶生物碱白屈菜赤碱的全合成。通过图3所示的两条路线制备的共同中间体(5)。
