Circular dichroism and optical rotatory dispersion of some hexahydroindanone derivatives; methyl- and methylene-substituted steroid ketones

Abstract

Circular dichroism and optical rotatory dispersion curves of a number of steroid hexahydroindanones have been measured. The compounds were A-nor-5α-androstan-2-ones and 5α-androstan-16-ones carrying methyl groups in positions adjacent to carbonyl. The curves are discussed in relation to the probable conformations of the cyclopentanone ring. Some data on related αβ-unsaturated ketones are also included.
