Abstract

Steroids U 0300Reactions of 5-Diazoimidazoles with Steroid Hydrazones. -The reaction of 5-diazoimidazoles, e.g. 5-diazo-4-nitroimidazole, with steroidal hydrazones such as (I) gives rise to corresponding imines [cf. (III)] instead of the desired tetrazenes [cf. (II)] due to the instability of compounds (II). -(SADCHIKOVA, E. V.; KURENEVA, E. A.; SHTOKAREVA, E. A.; SELEZNEVA, I. S.; Chem. Heterocycl.
