ALMEIDA, Claudia Lais Araujo et al. Benzamidoxime-Mediated Crotylation of Aldehydes using Potassium (Z) and (E)-Crotyltrifluoroborates. J. Mex. Chem. Soc [online]. 2018, vol.62, n.1, 00003. ISSN 1870-249X.  https://doi.org/10.29356/jmcs.v62i1.577.

A highly diastereoselective protocol for the crotylation reaction of aldehydes using potassium (Z) and (E)-crotytrifluoroborates was developed. Benzamidoxime was employed as a renewable catalyst, which was easily recovered through a simple extraction process. This method proved to be simple, fast, regio- and chemoselective for different aldehydes. The corresponding homoallylic alcohols were obtained in good to excellent yields without the need of further purification.

Palavras-chave : Crotylation reaction; homoallylic alcohols; benzamidoxime; potassium organotrifluoroborates.
