Cephalimysin A is a potent anticancer natural product and its structure remains to be fully elucidated. To solve the stereochemical issue, a stereoselective synthesis of its spirofuranone-γ-lactam core was performed in a cascade fashion. The absoluteconfiguration of key spiro stereogenic center was introduced based on d-malic acid derived imide and confirmed by a stereospecific derivatization.
