噻吨酮1是由硫代水杨酸甲酯以简洁的方式合成的，在可见光区具有显著的吸收。它允许一个有效的对映选择性催化分子内[2+2]光环加成反应，推测通过三重态能量转移。
Thioxanthone 1, which was synthesized in a concise fashion from methyl thiosalicylate, exhibits a significant absorption in the visible light region. It allows for an efficient enantioselective catalysis of intramolecular [2+2] photocycloaddition reactions presumably by triplet energy transfer.
