()-Renieramycin G was synthesized in 21 steps for the longest linear sequences employing L-tyrosine methyl ester as the chiral starting material in 8.5% overall yield. Two of the four chiral centers came from l-tyrosine methyl ester, and the other two were induced through an intermolecular and an intramolecular Pictet&150;Spengler reaction, respectively.
