## Abstract The reaction of carboxylic esters with ethylmagnesium bromide in the presence of titanium(IV) isopropoxide, which leads to the formation of substituted cyclopropanols, was disclosed in the late 1980β²s. The key organometallic intermediates in this transformation are diisopropoxytitanacyc

## Abstract The methylenation reaction of methyl azuleneβ2βcarboxylates (__cf. Schemes 1__ and __2__) with __Tebbe's__ or __Takai's__ reagent is described. When the prescribed amount of __Takai's__ reagent is applied in a fourβfold excess, the corresponding cyclopropyl methyl ethers are formed inst
Enantioselective Cyclopropanation of Allylic Alcohols with Dioxaborolane Ligands: Scope and Synthetic Applications. -Chiral dicarboxamidodioxaborolane is found to be a very efficient chiral controller for the conversion of allylic alcohols (I) to enantiomeric cyclopropylmethanols (III) using bis(io
