Abstract

To investigate the substrate preferences of O-methyltransferases in the monolignol biosynthetic pathways, caffeoyl and 5-hydroxy coniferyl aldehydes were synthesized by a new procedure involving a Wittig reaction with the corresponding hydroxybenzaldehydes. The same procedure can also be used to synthesize caffeoyl and 5-hydroxyconiferyl alcohols. Relative O-methyltransferase activities against these substrates were ...
