A rapid synthesis of 1,2,3,4-tetrahydro-7-hydroxyisoquinoline-3- carboxylic acid is given. Pictet-Spengler reaction on diiodo- or dibromo-substituted tyrosine (3-(3,5-dihalo-4-hydroxyphenyl)- 2-aminopropanoic acid), followed by catalytic dehalogenation gives the desired compound in high optical purity

This study presents a rapid synthesis of 1,2,3,4-tetrahydro-7-hydroxyisoquinoline-3-carboxylic acid, a conformationally constrained tyrosine analogue, using the Pictet-Spengler reaction on diiodo- or di
