Abstract
In an aprotic solvent, dimethylformamide, a coupling reaction between an α,β-unsaturated ketone and an aldehyde is achieved with chromium(II) chloride. An intermolecular aldol reaction and an intramolecular cyclization proceed sequentially to give cis-2-hydroxyalkyl-substituted cyclopropanol stereoselectively [Eq. (a)].
