摘要：

Functionalization of the (eta6-arene)tricarbonylchromium(0) complexes of some podocarpic acid (1) derivatives has been achieved via addition-oxidation methodology. The resulting decomplexed products underwent Lewis acid-mediated cyclopentaannulation to give ring-C aromatic androstane analogues in high yield. The D rings of these steroidal analogues were modified by both oxidation and reduction sequences, becoming structurally similar to some of the C15- or C17-oxygenated naturally occurring steroids.
