Spectinomycin modification. III Chloro-deoxy analogs

9-Epichloro-9-deoxy-4(R)-dihydrospectinomycin (3), 9-chloro-9-deoxy-4(R)-dihydrospectinomycin (7), 9-deoxy-8, 9-epimino-4(R)-dihydrospectinomycin (6), and 9-epichloro-9-deoxy-spectinomycin (10) have been prepared and their structures established by proton magnetic resonance. These analogs are devoid of antibiotic activity.
