A phenanthroindolizidine and phenanthroquinolizidine alkaloid having a hydroxyl group on the phenanthrene ring thereof was synthesized, which exhibits potent activity as an anticancer agent against, such as breast cancer, lung cancer, and prostate cancer.
Cyano Group Removal from Cyano-Promoted Aza-Diels–Alder Adducts: Synthesis and Structure–Activity Relationship of Phenanthroindolizidines and Phenanthroquinolizidines
Phenanthroindolizidines and phenanthroquinolizidines were concisely synthesized by the reductive decyanization of cyano-promoted intramolecular aza-Diels–Alder cycloadducts followed by aryl–aryl coupling. Cyano groups were removed from α-aminoacrylonitriles via treatment with sodium borohydride in 2-propanol in almost quantitative yields; a possible mechanism was proposed and examined using D-labeling experiments
