Using L-tyrosine as a chiral starting material, we developed an efficient synthetic route to (–)-MY336a. A key step in the sequence is a highly regio- and diastereoselective intermolecular Pictet-Spengler cyclization reaction between amino alcohol and benzyloxyacetaldehyde. J.

to these important antitumor alkaloids with high yields: (−)-jorunnamycin A, as a common precursor to other renieramycin-type alkaloids and their analogues, is obtained with 18.1% overall yield froml-tyrosine.
