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

small amounts ( < 5%). The exolendo ratio did not depend on the steric requirements of the substituents on C4 (OSiPh,, OSiBn,, OSitBuMe,). The em-directing influence arose exclusively from the effect of the 1,6-anhydro configuration. This observation has been confirmed with related monocyclic pseudo
