Popis:	The retro configuration (9β,10α) was introduced into pregnane derivatives containing substituents at C(16) and/or C(17) by irradiation of a suitable 5,7-diene. In this way the title compounds became much more accessible than by the introduction of ring D substituents into 20-ketoretro-steroids.
