Seldomycin factor

With primary or nonsterically hindered secondary alcohols, method A led exclusively to the formation of chlorinated sugars [68]. The mildness and efficiency of this chlorination method was used to advantage in the synthesis of a dichloro aminoglycoside, a precursor of seldomycin factor 2 [68] (Scheme 7). [Pg.131]

Several components have been separated from the seldomycin complex elaborated by Streptomyces hofunensis. Seldomycin factors 1 and 2 were identified as 6-0-(2-amino-2 deoxy-a-D-xylopyranosyl)paromamine (494) and 4 -deoxynea-mine, respectively factor 3 as, probably, (495) (i.e. the 6 -amino-6 -deoxy analogue of factor 1) and factor 5, which is the most active of these antibiotics, as 6-0-(2,3-diamino-2,3-dideoxy-4-0-methyl-a-D-xylopyranosyl)-4 -deoxyneamine (496 ... [Pg.153]
