Photosensitized 2 + 2 Cycloaddition Reaction Using Homochirality Generated by Spontaneous Crystallization

Photosensitized 2 + 2 Cycloaddition Reaction Using Homochirality Generated by Spontaneous Crystallization

A photosensitized reaction was performed using molecular chirality, which was generated and amplified by the spontaneous crystallization of achiral coumarincarboxamide. The molecular chirality was retained in a cold solution caused by slow racemization and was transferred to optically active product...

Zusammenfassung:A photosensitized reaction was performed using molecular chirality, which was generated and amplified by the spontaneous crystallization of achiral coumarincarboxamide. The molecular chirality was retained in a cold solution caused by slow racemization and was transferred to optically active products by a photosensitized 2 + 2 cycloaddition reaction with high enantiomeric excesses.
