10-b]indolizidin-9-ones, phenanthro[9,10-b]quinolizidin-9-one, and related benzolactams were synthesized by benzolactam ring formation using Pd(OAc)2-catalyzed direct aromatic carbonylation. This also constitutes a formal synthesis of the representative phenanthroindolizidine and -quinolizidine alkaloids (±)-tylophorine, (±)-antofine, and (±)-cryptopleurine.(© Wiley-VCH Verlag GmbH & Co.

菲 [9,10-b] indolizidin-9-ones、菲 [9,10-b] quinolizidin-9-one 和相关苯并内酰胺是通过使用 Pd(OAc)2 催化的直接芳香羰基化通过苯内酰胺环形成合成的。这也构成了代表性的菲吲哚里西啶和-喹唑西啶生物碱 (±)-tylophorine、(±)-antofine 和 (±)-cryptopleurine 的正式合成。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
