Although the development of organic products have been a decisive factor in rapid development for the last two centuries, hazardous solvents, nonbiodegradable catalysts, and long reaction times have always been a serious issue in organic synthesis. The solution to all issues highlighted above lies in the environment-friendly synthesis and green chemistry. In such synthesis, reaction time is decreased by using energy-efficient methods of heating (like microwave irradiation), high yield, biodegradability, good selectivity of solvents, good performance of catalysts, and usage of environment-friendly greener solvents like water, ethanol, acetone, etc. in an all-in-one approach [1]. Auxins, a class of naturally organic compounds, are plant growth hormones found in and required by plants in very little amounts, yet their presence is very critical. This class of compounds contain acetic acid-based Pol. AbstractPreparing novel compounds using environment-friendly protocols for plant growth has remained a major goal for plant scientists. In this research, effect of a novel plant growth promoter on sunflower (Helianthus annuus L.) was assessed hydroponically as well as in soil acclimatized plantlets at 1, 10, and 100 µM. The plants were also assessed for antioxidant enzymatic and antifungal activities. The synthesized derivative 2 produced significantly better results in terms of overall growth as compared with standards at 1 µM concentration among all compounds. Increased catalase and superoxide dismutase levels in plant seedlings treated with synthesized compounds were observed when grown in hydroponics, but these values were found to be significantly low as compared to soil-acclimatized plants. No significant zone of inhibition was found on agar plates in antifungal bioassay.

Better plant growth of crop plants has been a major concern of mankind since antiquity. Indole acetic acid is one of the natural plant growth regulators studied in plant sciences for a long time, followed by cytokinins, ethylene, gibberellic acid, and others that were discovered later. Indole acetic acid is responsible for promoting root growth while cytokinins like zeatin are considered specialized for shoot growth [1]. Later on, the attention of scientists was diverted toward commercial production of
