Bleomycin A2 has been synthesized for the first time. Bleomycin (BLM) is an antitumor antibiotic clinically used in the treatment of squamous cell carcinoma, malignant lymphoma and testis tumors. BLM A2 (Q2), the major component of natural BLMs, consists of a linear hexapeptide named deglyco-BLM A2

An improved route to synthesize deglyco-bleomycin A2, the aglycon of bleomycin A2, aiming at the total synthesis of bleomycin is described. The new route is characterized by the stepwise elongation of the amino acid constituents and the use of a thiol ester obtained by aldol condensation. Deglyco-b
