Significance

The authors describe a novel preparation of chiral difluoroallylboronates and their application to the difluoroallylboration of various aldehydes. The α-gem-difluorohomoallyl alcohol products are obtained in good yields with 77-95% enantiomeric excess and can be used to synthesize chiral α-pyrones.
