Significance

Non-racemic homopropargylic alcohols are important intermediates for the synthesis of different classes of useful compounds. This approach offers the use of readily accessible and recoverable chiral auxiliary, along with excellent selectivity and simplicity of the whole process. Allenylmagnesium bromide serves as a convenient C3-chain source without the need of using tin or silicon intermediates.
