Indoles and hydantoins are important heterocycles scaffolds which present in numerous bioactive compounds which possess various biological activities. Moreover, they are essential building blocks in organic synthesis, particularly for the preparation of important hybrid molecules. The series of hybrid compounds containing indoles and imidazolidin-2-one moiety with direct C-C bond were synthesized using an amidoalkylation one-pot reaction. All compounds were investigated as a growth regulator for germination, growth and development of wheat seeds ( L). Their effect on drought resistance at very low concentrations (4 × 10 M) was evaluated. The study highlighted identified the leading compounds, a and e, with higher growth-regulating activity than the indole-auxin analogues.
