Aromatic hydroxylation of methyl cinnamate to methyl 4-hydroxycinnamate catalyzed by the cell-free extracts of a brown-rot fungus Lentinus lepideus

Aromatic hydroxylation of methyl cinnamate to methyl 4-hydroxycinnamate catalyzed by the cell-free extracts of a brown-rot fungus Lentinus lepideus.Several substances are used for example 832-01-9 and 7400-08-0 which are their cas registry numbers.

DOCUMENT TYPE: Journal CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 10, 16 A new arom. hydroxylase which catalyzes the hydroxylation of Me cinnamate to form Me 4-hydroxycinnamate was extd. in a cell-free form from the mycelia of the brown-rot fungus L. lepideus. This enzyme also hydroxylates cinnamic acid to 4-hydroxycinnamic acid, but the hydroxylation rate for this acid is ~1/3 that of Me cinnamate. A new biosynthetic pathway leading from L-phenylalanine to the major secondary metabolite Me 4-methoxycinnamate in this basidiomycete is proposed. .

DOCUMENT TYPE: Journal CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Cellulose-supported palladium(0) catalyst was prepd. and applied to the Heck and Sonogashira coupling reactions by treating aryl iodides with alkenes and phenylacetylene, resp., to afford coupled products in good to excellent yields. The catalyst was recovered by simple filtration and reused for several cycles. .
