diorganocuprates to ⇌,β-unsaturated ketones and regiospecific trapping of the resulting enolate with ⇌-trimethylsilyl vinyl ketones is presented. The stereochemical details of the process have been elucidated and are discussed. Application of this methodology to the synthesis of a variety of polycyclic ketonestructures is described including applications to steroid synthesis.

The tricyclic enone 12, containing the taxane ring system, has been synthesized, using an intramolecular Ni(II)/Cr(II)-mediated coupling of beta-iodoenone aldehyde 11 as the key step.
