| Abstract: | The determination of the absolute configuration of the trichloro steroids 2a and 2c (cf. Scheme 1) by means of two X-ray crystal structure analyses is reported and applies also to the determination of the absolute configurations of several derived steroidal cyclopropanes 1]. The preparation of the chlorinated derivatives 2a-c is described and the spectroscopic properties of 1 and 2 are summarized. |
