Several conformationallyrigidanalogues of the methylvalerate subunit contained within the linker domain of the antitumor antibiotic bleomycin have been prepared. These compounds have been protected in a fashion suitable for the solid-phase synthesis of bleomycin. Bleomycin congeners containing these analogues should facilitate a more detailed understanding of the nature of the conformational bend that
