While searching for the directions of synthesis of compounds with plant growth regulation properties, an estimation was done of the substituent effect at the carbamate nitrogen atom upon compounds of the carbamate series. It was found that the introduction of α-naphtyl substitution produces specific induction effects and izomerization rearrangements that do not favour biological activity. In the postemergence test, N-cyclohexyl 0-(2-methyl-2-aminopropyl) carbamate inhibited the growth of bean seedlings and affected chromosomes in cytological tests.
