The novel photoisomerization of 1-acylindoles accompanied by a conversion of indole to indolenine afforded 3-acylindolenines, a so far unknown reactive species, as a major product. This reaction was thorougly investigated and applied with success to the total synthesis of Strychnos, Aspidosperma, Schizozygane and Eburnamine alkaloids through a versatile intermediate 9-membered ring system, synthesized
1-acylindoles的新型光异构化伴随吲哚向吲哚烯的转化,提供了3-acylindolenines(一种迄今未知的反应性物种)作为主要产物。对该反应进行了彻底的研究,并成功地通过通用的中间9元环系统,通过光解和同时扩环在一个锅反应中合成了马钱子,曲霉,裂殖子和依加胺生物碱的全合成。
