Totalsynthesis of leucinostatin A, a modulator of tumor‐stroma interactions, using asymmetric catalyses, a nitroaldol reaction, thioamide‐aldol reaction, Strecker‐type reaction, and alcoholysis of 3‐methylglutaric anhydride, is described. We demonstrated the applicability of the established catalyticasymmetric processes to the synthesis of molecules with a complex structure. Careful analysis of the
