Titanium(IV) Isopropoxide-Catalyzed Formation of 1-Substituted Cyclopropanols in the Reaction of Ethylmagnesium Bromide with Methyl Alkanecarboxylates

ChemInform Abstract In the presence of equimolar amounts of Ti(OiPr)4 the reaction between the carboxylic esters (I) and EtMgBr (II) affords the 1-substituted cyclopropanols (III) in high yields. This reaction offers a convenient access to cyclopropanols. The mechanism is, so far, not clear.
