A new versatile synthetic methodology for the synthesis of enantiomerically pure natural phenanthroindolizidines and phenanthroquinolizidines has been established and described. Natural products R-antofine and R-cryptopleurine, as well as a novel E-ring expanded analogue 13c (E7), 12-oxo-S-antofine (17), and 12N-methyl-12-aza-S-antofine (18) were synthesized with the new method. This strategy will greatly facilitate future SAR studies on the natural alkaloids with E-ring variations.
建立并描述了一种新的通用合成方法,用于合成对映体纯的天然菲并吲哚里嗪和菲并喹啉里嗪。利用新方法合成了天然产物 R-阿替非宁和 R-隐石松宁,以及一个新型 E 环扩展类似物 13c(E7)、12-氧代-S-阿替非宁(17)和 12N-甲基-12-氮杂-S-阿替非宁(18)。该策略将极大地促进未来对具有 E 环变化的天然生物碱的 SAR 研究。
