The 1,3-dipolarcycloaddition reaction of isoquinolinium ylides to nitrostilbenes provides an approach to 1,2-diarylpyrrolo[2,1-a]isoquinolinium-3-carboxylates and then to a complete hexacyclic lamellarin core.

related natural products based on Barton–Zard reaction of nitrostilbenes with ethyl isocyanoacetate was developed. Treatment of diarylpyrrole‐2‐carboxylates with 1 equiv. of. BBr3 resulted in selective O‐demethylation of the ortho‐methoxy group, while other methoxy groups remained intact. Subsequent base‐induced lactonization provides the target pyrrolocoumarins.
