Using L‐tyrosine as a chiral starting material, we developed an efficient synthetic route to (–)‐MY 336a. A key step in the sequence is a highly regio‐ and diastereoselective intermolecular Pictet‐Spengler cyclization reaction between amino alcohol and benzyloxyacetaldehyde. J. Heterocyclic Chem., (2010).

## Abstract A new approach that tried to obviate the use of bromine protection groups was studied to synthesize (−)‐renieramycin G from L‐tyrosine. It was found that the first intermolecular Pictet–Spengler reaction proceeded successfully to give the correct tetrahydroisoquinoline precursor **6**.
