5,6-dihydropyrrolo[2,1-b]isoquinolines as scaffolds for synthesis of lamellarin analogues

摘要

Efficient modular synthetic routes to open chain marine alkaloids such as lamellarins have been developed. 5,6-Dihydropyrrolo[2, 1-b]isoquinoline scaffolds were prepared, and protocols enabling regioselective bromination followed by Suzuki cross-coupling were established for the introduction of aryl groups onto the 2- and 3-positions.
