Studies on Lignin

Abstract

Two new phenylpropane derivatives, 1-(4-hydroxy-3-methoxyphenyl)-propanediol-(1, 2) and 1-(4-hydroxy-3-methoxyphenyl)-propanediol-(1, 3) were synthesized as lignin model compounds. The former was prepared from 2-acetoxy-l-(4-acetoxy-3-methoxyphenyl)-propanone-(1), and the latter from 3-acetoxy-l-(4-acetoxy-3-methoxyphenyl)-propanone-(1) by lithium aluminum hydride reduction, respectively. The two diols were obtained as colorless syrup, their ultraviolet spectra were determined and crystalline derivatives also prepared.
