synthesized in high yields from an aryl amine and a 5-amino-3-oxopentanoate derivative through a series of reactions of enamination, oxidative annulation, deprotection/lactamization and the final reduction reaction of the carbonyl group. The underpinning strategy involves the oxidative C(sp2)–C(sp2) bond formation realized by either Pd(OAc)2/Cu(OAc)2 or a hypervalent iodine reagent.
合成和生物学上重要的4-甲基和4-甲氧基四氢-γ-咔啉化合物易于通过芳基胺和5-氨基-3-氧opentanoate衍生物通过一系列的引发,氧化环化,脱保护反应高收率合成。内酰胺化和羰基的最终还原反应。支撑策略涉及通过Pd(OAc)2 / Cu(OAc)2或高价碘试剂实现的氧化C(sp 2)–C(sp 2)键形成。
