GREEN APPROACH FOR THE PREPARATION OF 2-ARYL-1, 3-BENZOXAZOLE DERIVATIVES BY USING Amla Fruit EXTRACT

Abstract

One pot, rapid and green preparation of 2-aryl-1,3-benzoxazole and their derivatives via the reaction of o-amino phenol and substituted aryl aldehydes by using amla fruit extract at room temperature or under microwave radiation. Amla fruit extract is a biocatalyst associated with low-cost, inexpensive, non-volatile, and environmentally friendly. The prepared catalyst shows many chemical, phytochemical, and anti-oxidant constituents, which are unfavorable to increase the acidic contents of water extract. The noteworthy benefits of this process are simple, easy methodology, an excellent yield of product, minimum time of reaction, ease of separation, easy work, and green catalyst. The prepared compound where characterized by analytical or spectroscopic techniques such as FT-IR (infrared) spectrum, H1-NMR, C13-NMR, and LC-MS (Mass) analysis.
