title: Enantioselective synthesis of 2-substituted cyclobutanones
abstract: [formula: see text] An enantioselective synthesis of 2-substituted cyclobutanones has been achieved by sequential application of the titanium-mediated cyclopropanation of alpha-hydroxy esters and the pinacol-type rearrangement of the resulting alpha-hydroxycyclopropylcarbinols.
