Organocatalytic Enantioselective [3+3] Annulation toward Chromene-Fused Helicenes Bearing Central and Helical Chirality With Chiroptical Properties

The enantioselective catalytic construction of structurally sophisticated helicenes integrating both helical and central chirality remains a formidable challenge, and organocatalytic strategies for helicene synthesis are still severely underexplored compared with transition-metal catalysis. Benefiting from the inhere...
