PROCESSES FOR CONVERSION OF TYROSINE TO P-HYDROXYSTYRENE AND P-ACETOXYSTYRENE |
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. |
