Spanish abstract Se desarrolló un protocolo altamente diastereoselectivo para la reacción de crotilación de aldehídos usando potasio (Z) y (E)-crotitrifluoroboratos. La benzamidoxima se empleó como catalizador renovable, que se recuperó fácilmente mediante un proceso de extracción simple. Este método demostró ser simple, rápido, regio- y quimioselectivo para diferentes aldehídos. Los alcoholes homoalílicos correspondientes se obtuvieron con rendimientos buenos a excelentes sin la necesidad de una purificación adicional
English abstract 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
