- Abstract
Synthesis of two lamellarin derivatives, that is, naphthoquinone‐fused pyrrolo[2,1‐a]isoquinoline and tridemethoxy lamellarin D was reported. The former was synthesized by Lewis acid‐catalyzed oxidative cyclization of 6,7‐dimethoxynaphthalene‐1,4‐dione and papaverine to form the pentacyclic scaffold. The latter was prepared via base‐mediated Grob coupling of 1‐methylisoquinoline and 7‐methoxy‐3‐nitrocoumarin as a key step to construct the lamellarin skeleton.
