synthesis of functionalizedphenolic α-amino-alcohol (±)-13 as synthetic precursor of the catechol tetrahydroisoquinoline structure of phthalascidin 650 is disclosed. Starting from 3-methylcatechol 5, eight steps of synthesis give rise to the synthesis of phenolic α-amino-alcohol (±)-13 in 27% overall yield. This synthetic strategy involves the elaboration of fully functionalized aromatic aldehyde 8 and its
