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.
酪氨酸经过两步反应转化为对羟基苯乙烯,中间体没有经过单独纯化。确定了溴化酪氨酸的条件,生成了活性中间体。这些中间体的混合物直接用于第二步反应,产生对羟基苯乙烯。对羟基苯乙烯在第二步反应容器中进一步乙酰化,生成对乙酰氧基苯乙烯。
