of reactions under VLPC are photosynthesis mimic reactions, and the chemists brought the process into action at the laboratories.

VLPC strategies developed by chemists in recent years portrait the esthetic taste and the design of energy-saving and environmentally compatible and benign features in this innovative domain of organic synthesis.

Among all the subdisciplines of catalysis, the newly emerged gifted child, namely, visible-light photoredox catalysis, has grown rapidly and has made a great of deal of interest in both academia and industry; in the near future, we will be witnessing the process development of drug molecules.

The twin catalysis comprising a chiral agent and the transition metal catalyst brought forward the asymmetric synthesis in a one-pot synthetic fashion in this neoteric protocol which portraits the highest level of creativity of synthetic chemists. Consequently, it can be construed that from the catalytic professionals, more VPLC protocols will emerge to attain pharmaceutically active ingredients through industrial manufacturing processes, especially in enantiomerically enriched forms.

In terms of kinetics, not much work is done, and such research articles are expected in the pipeline; much work has to be done on the recyclability and reusability of catalytic materials including the studies on leaching.

It is interesting to note that only in this domain the methodology quickly reached to the stage of asymmetric synthesis in a rapid way, implying the success in the process development of drug molecules; subsequently, more process developments are expected as the industrial process.
