A short formal total synthesis of the marine natural product diazonamide A is described. The route is based on indole oxidative rearrangement, and a number of options were investigated involving migration of tyrosine or oxazole fragments upon oxidation of open chain or macrocyclic precursors. The final route proceeds from 7‐bromoindole by sequential palladium‐catalysed couplings of an oxazole fragment

Conversion of 3-iodo-L-tyrosine to protected tyrosine-3-boronate esters, followed by oxidation with hydrogen peroxide, provides a mild and efficient method for the preparation of selectivelyprotectedL-dopaderivatives.
