Coumarin‐Based Heteroaromatics as Plant Growth Regulators

Heterocyclic compounds are the largest and most versatile class of organic compounds. Plants produce valuable heterocyclic substances called phytohormones to carry out the growth process. They control the growth or other physiological functions. Both hormones and vitamins are generally referred as plant growth regulators. Aromatic compounds having lactone ring are called coumarin. Coumarin is one of the most important natural substances in plants and is referred to as anti‐auxins, as these compounds are considered to play an essential role in plants growth as well as defense

A REVISIT OF PECHMANN REACTION UNDER MICROWAVE RADIATION

A series of coumarins have been prepared by the Pechmann reaction of different phenols with ethyl acetoactate as well as malic acid using catalytic amount of sulfuric acid under microwave irradiation for few seconds.   Keywords: Pechman reaction, Coumarins, Microwave irradiatio
