Circular dichroism of some cyclopropane ring containing 1,3-cyclo-5,10-seco-steroidal ketones
Abstract
Circular dichroism of the rearranged keto steroids 3 and 4, containing a condensed three and nine-membered ring system, shows that the conformation of the nine-membered ring is the same in solution as in the crystal; reduction of the kto group does not change this situation. CD also indicates that epimerization at C(5) in the pair 7 8 and the pair 11 12 leaves the cyclononanone ring conformation unchanged. © 1982.
