A straightforward synthesis of magallanesine 1 from azetoisoquinoline 4 has been accomplished via [1,2]-Meisenheimerrearrangement and an intramolecular Heck cyclization as the key reactions.
A straightforward total synthesis of magallanesine 1 was accomplished from readily available isoquinolineacetate 14. This synthesis is emphasized by the following two points; i. the [1,2]-Meisenheimerrearrangement of the azetidine N-oxide 22 for the preparation of azocine ring, ii. the Pd-catalyzed intramolecular Heck reaction of N-benzoylenaminone 38 for the construction of isoindoloazocine skeleton
