Title compds. [III(or IV); R1 = R4 = H, C2-3 alkanoyl; R2 = C2-3 alkanoyl; R3 = H , useful as fungicides, were prepd. by the reduction of I(or II; Y1 = NH, N-OH, N-OCOCH3; Y" = NH). Thus, 14.0 g 2'-acetyl-4"-deoxy-4"-oxoerythromycin A O-acetyl oxime was reduced with 60 g Ra-Ni catalyst at room temp, 1000 psi in 400 ml iso-propanol to give 8.1 g 2'-acetyl-4"-deoxy-4"-amino-erythromycin A.
