Chiral Discrimination in Photochromic Helicenes
A photoresponsive dithienylethene derivative bearing chiral pinene-based arms underwent a stereoselective photoinduced cyclization reaction to produce greater than 98% of a single diastereomer. The magnitude of the optical rotation changed as much as Δ[α]373 = 8698° upon alternate irradiation with 4...

| description | A photoresponsive dithienylethene derivative bearing chiral pinene-based arms underwent a stereoselective photoinduced cyclization reaction to produce greater than 98% of a single diastereomer. The magnitude of the optical rotation changed as much as Δ[α]373 = 8698° upon alternate irradiation with 400 nm and greater than 434 nm light. |
