Abstract
In the quest for new agrochemicals and pharmaceuticals,chemists seek access to reliable and mild syn-thetic techniques to allow for the systematic modification of chemical structures,exploration of unex-plored chemical space,and facilitation of practical synthesis in their search for novel agrochemicals and pharmaceuticals.In this regard,photocatalytic reactions enabled the synthesis of intricate and more func-tionalized compounds.This review overviews the developed synthetic methodologies and their utility in the chemical synthesis of pharmaceuticals.This review also offers in-depth insights into contemporary photoredox reactions such as allylic additions,cyclization,reductive cross-coupling,C-H activation,ring opening,oxidative cross-coupling,dehydrogenation,desulphonation,and decarboxylation.It provides a positive outlook for the promising future of this field.
