Abstract

The synthesis of compounds <i>VII, XVII, XXXIV</i> and <i>XXXVII</i> is described, in which biological activity is assumed. The key steps of their preparation are the dehalogenation of compound <i>XVIII</i> and radicalic deoxygenation of the 6β-hydroxy group in compound <i>XXX</i>, which take place without skeletal rearrangements.
