title: Total synthesis of (-)-raumacline.
abstract: The total synthesis of (-)-raumacline from L-tryptophan was achieved, featuring a cis-specific Pictet-Spengler reaction, a stereoselective Dieckmann cyclization, and an epimerization step that allowed complete stereocontrol of five chiral centres.
