Psicose nucleosides

The sugars from the nucleoside-like antibiotics have been discussed in Section III,5. These are cordycepose (29), D-psicose (30), angustose (33), and amicetose (39). From actinospectacin, the unusual actinospectose (46) was obtained. Hygromycin and hygromycin B have yielded two novel products, 6-deoxy-D-om6mo-hexos-5-ulose (49) and D-talose (51). Novobiocin contains the sugar derivative called noviose (54).
