New growth regulators of corn based on N-mono- and N,N-bis-3-butenyldichloroacetamides

Abstract

Allylboration of imines, nitriles (including hydrocyanic acid), amides, lactams, aromatic azaheterocycles (pyridines, isoquinoline, and pyrrole) was used to synthesize a series of mono- and bis-3-butenylamines with different structures, which were converted to dichloroacetamides, new analogs of a known safener (herbicide antidote) Dichlormid successfully used in the cultivation of corn throughout the world. Biological tests for the germination of corn seeds showed that most of the dichloroacetamides obtained have growth-stimulating activity, which is mainly directed on the development of the root system. Compounds 2f, trans- and cis-2n, cis-2s, and 2t demonstrated outstanding activity, exceeding from two to three times the stimulating effect of Dichlormid on the developing root system of maize seedlings.
