STEROIDAL OXAZOLES, OXAZOLINES, AND OXAZOLIDINES

In recent years the interest of this investigator has been attracted t o a series of new compounds in which a cyclopentanoperhydrophenanthren e system is condensed with various heterocyclic rings. As was to be ex pected, the addition of heterocycles to steroids often leads to a chan ge of their physiological activity and the appearance of new interesti ng biological properties. Since the numerous data on the synthesis and properties of the steroidal oxazoles, oxazolines, and oxazolidines ar e scattered, this stimulated us to write the present review, in which the literature published up to the end of 1994 is systematized.
