    摘要： Three different reaction steps were combined to provide methods for preparing p-hydroxystyrene and p-hydroxycinnamic acid monomers from tyrosine. The three steps include reductive alkylation of tyrosine, followed by oxidation to the N-oxide, and thermal Cope elimination. During Cope elimination, either p-hydroxycinnamic acid or p-hydroxystyrene was produced depending on the absence or presence of base, respectively. Additionally, p-acetoxystyrene may be prepared by reacting the prepared p-hydroxystyrene either directly or after isolation with an acetylating agent.

    摘要： Disclosed is a method for the combined synthesis of at least two vinylic monomers, at least one of which being an acrylic compound, comprising subjecting a monoconjugated alkene-1-carboxylic compound to reaction with a C2-C4 alkene under conditions of olefin cross-metathesis. The invention is particularly useful for extracting value from protein side streams. Upon protein hydrolysis, suitable amino acids (preferably phenylalanine or tyrosine) are subjected to reductive amination so as to form the corresponding alkene-1-carboxylic acid. Preferably after esterification and separation, this is used in cross-metathesis for the concomitant production of styrene resp. hydroxy styrene, and acrylates. The invention is applicable more widely, to the synthesis of olefins on the basis of carbohydrates, naturally occurring phenolic components, natural protein resources, or amino acids obtained from fermentations.

    摘要： Tyrosine was converted to p-hydroxystyrene in a two-step reaction without purification of individual intermediates. Conditions were determined for bromination of tyrosine in which reactive intermediates were formed. The mixture of these intermediates was used directly in a second step reaction to produce p-hydroxystyrene. The p-hydroxystyrene was further acetylated to produce p-acetoxystyrene in the second step reaction vessel.
