摘要:
                                N-Benzoyl-N'-carboxyl substituted thiourea derivatives (I-X) have been synthesized by the reaction of benzoyl isothiocyanate with amino acids. Their structures are confirmed by IR, (HNMR)-H-1, and elemental analysis. The reaction conditions are experimentally investigated, and the preliminary biological tests show that some of the compounds have excellent plant growth promotion activities.
