Facile Synthesis of 4-Hydroxycinnamyl p-Coumarates

Coniferyl p-coumarate (4-hydroxy-3-methoxycinnamyl 4-hydroxycinnamate) and sinapyl p-coumarate (3,5-dimethoxy-4-hydroxycinnamyl 4-hydroxycinnamate) were synthesized in high overall yield. In this improved method acetate was used as the phenol protecting group instead of 2,4-dinitrophenyl ether; selective deacetylation, without cinnamate ester hydrolysis, was accomplished with neat pyrrolidine.

P-coumaroylated syringyl units in maize lignin: Implications for β- ether cleavage by thioacidolysis

Recent NMR studies of lignin isolated from maize demonstrated that p- coumarate esters are attached exclusively to the T-position of phenylpropane side chains. Thioacidolysis/desulphuration experiments have revealed that p- coumarate units are attached pr
