Thallium Trinitrate Mediated Ring Contraction of Monocyclic Ketones: Stereochemical Aspects.

-Treatment of alkylcyclohexanones (I) or (IV) with thallium(III) nitrate induces ring contractions to cyclopentanecarboxylic acids (II), (III), and (V), with high degree of stereoselectivity and regioselectivity. 2,6-Dimethylcyclohexanone (VI) does not undergo this reaction. -(FERRAZ, H.
