An avenue to homotyrosinol derivatives through a Heck coupling of 4-iodophenyl acetate with a vinylglycinol derivative required extensive screening of catalysts and conditions. The use of Pd(OAc)2 and N-phenylurea as the ligand ultimately provided excellent results. coupling - Heck reaction - homotyrosine - palladium - N-phenylurea
通过乙酸4-碘苯基苯酯与乙烯基甘醇衍生物的Heck偶联来制备高酪氨醇衍生物的途径需要对催化剂和条件进行广泛的筛选。最终使用Pd(OAc)2和N-苯基脲作为配体。 偶联-Heck反应-高酪氨酸-钯-N-苯基脲
