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
