Photoredox catalysis with 10-phenyl-10H- phenothiazine and synthesis of a photocatalytic chiral proline-based organocatalyst
Abstract: Photoredox catalysis applications for the purpose of new synthetic routes in organic and sustainable chemistry are hot topics in organic synthesis today. In the present study, the synthesis of a chiral proline-based organocatalyst functionalized with 10-phenyl-10H phenothiazine (PTH) photocatalytic moietiesis investigated and attempted for the first time. PTH, an organic photocatalyst, isstudied for its photocatalytic activity in different organic reactions, such as dehalogenation of aromatic halides and the pinacol coupling reaction between aromatic aldehydes. These transformations are otherwise difficult to achieve without a suitable catalyst and the reactions were performed with moderate to high yields.
