Study on synthesis of plant growth hormone indole-3-butyric acid

Abstract

The indole-Bsbutyric acid (IBA) is an important plant growth stimulator. Its synthesis has been carried out by different ways. Some methods for preparation of IBA were discussed. In this work, the compound was synthesized by two methods: reacting indol with γ -butyrolactone and gramine with diethylmalonate. However, the reaction of indol with γ-buryrotuctone in tetralin as solvent is realized in tile more acceptable conditions of pressure and temperature therefore can continue the study for application in practice.
