Abstract
Alkylation of 1- and 2-naphthols with propargyl bromide in acetone in the presence of potassium carbonate led to prop-2-ynyloxynaphthalenes, which upon reaction with 1-alkyl-piperidin-4-ones under the Favorsky conditions afforded the corresponding tertiary alcohols. 1-Methyl-4-[3-(2-naphthyloxy)prop-1-ynyl]piperidin-4-ol hydrochloride was found to possess a high growth-promoting activity in the concentration of 0.001% upon the pre-sowing treatment of beetroot seeds and potatoes and increase their productivity by ∼20%.
