A new efficient method for the synthesis of 1,4-dihydroxy-
2‑naphthylmethyl- and 1,4-dioxo-2(1H,4H)-2-naphthylmethylphosphonium
salts by reactions of 2-methyl-1,4-naphthoquinone
with appropriate P–H-phosphonium trifluoroacetates
has been suggested. The reactions were carried out under mild
conditions and provided high yields of target compounds.
Representative reaction products have been found to possess
moderate antimicrobial
and antitumor activity.
