Cinchona alkaloid-derived organocatalysts are widely employed in various asymmetric transformations, yielding products with high enantiopurity. In this respect, a bifunctional quinine-derived sulfonamide organocatalyst was developed to catalyze the a

We report a boron dipyrromethene that is chiral at boron and carbon (B*C*-BODIPY) and accessible through a two-pot, one-step synthesis-an interrupted Knoevenagel condensation. The electronic circular dichroism spectra of chiral high performance liqui

Squaramide/cinchona alkaloid-derived bifunctional organocatalysts are in high demand in asymmetric transformations. Bifunctional quinine-derived sterically encumbered squaramide (H-bond donor) organocatalysts were used to catalyze the asymmetric Frie
