Isoprenylation, aldehydes/ketones

The activated zinc obtained by electrochemical reduction of Zn2+ in dimethylformamide has been used for the isoprenylation of aldehydes and ketones. This has been reported by Tokuda and coworkers (equation 4)10. [Pg.760]

The isoprenylation of isovaleraldehyde led to the product in 68% isolated yield, higher than with a conventional procedure using zinc dust in DMF, or refluxing THF. The same procedure was used for the coupling reaction of allylic bromides with aldehydes and ketones, via the preliminary formation of organozinc compounds coming from the reaction between the electrolytic zinc and allylic bromides12. [Pg.760]
