A highly diastereoselective annulation strategy for the synthesis of alicyclic ketones from diols and pentamethylacetophenone is described. This process is mediated by a commercially available iridium(III) catalyst, and provides efficient access to a wide range of cyclopentane and cyclohexane products with high levels of stereoselectivity. The origins of diastereoselectivity in the annulation reaction have been explored by a series of control experiments, which provides an explanation for how each stereocentre around the newly forged ring is controlled.

The conjugate addition of Ti "ate" complexes of ketone and ester enolates to α,β-unsaturated carbonyl compounds was studied. The reaction was found to be highly regio- and stereoselective. Compared to the lithium enolates, ketone enolate Ti complexes show
