Peptide antibiotic, Leucinostatin D, was synthesized by stepwise elongation method, starting from beta-alanine t-bytyl ester. Z-octapeptide ester was converted to amide derivative and finally coupled with (4S,E)-4-methylhex-2-enoyl-L-4-methylproline.
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
