Concise Syntheses of Dictyodendrins A and F by a Sequential C-H Functionalization Strategy
Syntheses of dictyodendrins A and F have been achieved using a sequential C-H functionalization strategy. The N-alkylpyrrole core is fully functionalized by means of a rhodium(I)-catalyzed C-H arylation at the C3-position, a rhodium(II)-catalyzed double C-H insertion at the C2- and C5-positions, and a Suzuki-Miyaura cross-coupling reaction at the C4-position. The syntheses of dictyodendrins A and F were completed by formal 6p-electrocyclization to generate the pyrrolo[2,3-c]carbazole core of the natural products.
