    The synthesis of isoquinoline, a widely used antimalarial and antitubercular drug, has been a topic of significant research in the chemical industry.
    The most commonly employed synthetic route for isoquinoline involves the reaction of anthranilic acid with 2-chloro-1,3-oxazole in the presence of an acid catalyst.


    Anthranilic acid, the starting material for this synthesis, is readily available commercially and is relatively inexpensive.
    2-chloro-1,3-oxazole is also easily accessible and is commonly used as a synthetic intermediate in the production of a variety of pharmaceuticals.
    The reaction is carried out in the presence of an acid catalyst, such as hydrochloric acid or sulfuric acid, to facilitate the formation of the desired product.


    The reaction proceeds through a sequence of steps, involving the formation of an enamine intermediate and its subsequent heterocyclization to form the isoquinoline ring system.
    The reaction is generally carried out at moderate temperatures and pressures and provides a good yield of the desired product.


    Another synthetic route to isoquinoline involves the reaction of 4-methyl-3-nitro-2H-pyrazone with chloroform in the presence of a base such as sodium hydroxide.
    This reaction also leads to the formation of the isoquinoline ring system and can be used as an alternative to the anthranilic acid-based synthesis route.


    In recent years, there has been increasing interest in the development of alternative synthetic routes to isoquinoline, as the traditional methods may be costly or limited by environmental concerns.
    One such alternative involves the use of microwave irradiation as a synthetic tool.
    This method involves the use of high-frequency electromagnetic radiation to accelerate the reaction kinetics and provide a more efficient synthesis of isoquinoline.


    Another promising approach involves the use of enzymes as synthetic catalysts for isoquinoline synthesis.
    Enzymes offer several advantages over traditional synthetic methods, including reduced reaction times, improved selectivity, and reduced environmental impact.
    One such enzyme, phenylalanine ammonia lyase, has been successfully used in the synthesis of isoquinoline and holds great promise as a sustainable and environmentally friendly method for the production of this important pharmaceutical compound.


    In conclusion, the synthesis of isoquinoline has been the subject of significant research in the chemical industry, with several established synthetic routes currently in use.
    However, there is ongoing interest in the development of alternative methods that may offer cost savings or environmental benefits.
    Microwave irradiation and enzymatic catalysis are two promising approaches that hold great promise for the future of isoquinoline synthesis.
