The Evans-Chan-Lam variant of the Ullman condensation has been explored to deliver O-arylated tyrosines and tyrosinyl peptides. Key modifications for success were the slow addition of boronic acids to the phenol-catalyst mixture. Selectivity and scope are investigated.
Evans-Chan-Lam改型的Ullman缩合反应经过探究,用于合成O-芳基化的酪氨酸和酪氨酰肽。成功的关键在于将硼酸缓慢加入苯酚与催化剂的混合物中。对选择性和适用范围进行了研究。
