Epiandrosterone derivatives-organocatalyzed asymmetricMichaeladdition of aldehydes to nitroalkenes was investigated. Among the various catalysts, a novel type of epiandrosterone-derived L-prolineamide catalyst was synthesized and exhibited better performance in both catalytic activity and stereoselectivity, providing the products with high yields (up to 98%), excellent enantioselectivities (up to
Polycyclic heteroarenes are important scaffolds in the construction of pharmaceuticals. We have previously developed a series of novel heterocyclic iodoniums. In our current work, these unique iodoniums were employed to construct various complex polycyclic heteroarenes with structural diversity via tandem dual arylations. As a result, indole, thiophene and triphenylene motifs were fused into these
