2-Bromoallyl Acetate: A Useful Structural Unit for Sequential Carbon−Carbon Bond Formation
摘要:
[GRAPHICS]2-Bromoallyl acetate has been shown to be an efficient substrate for Ni(II)/Cr(II) mediated coupling reactions with a variety of aliphatic and aryl aldehydes, Surprisingly, elimination of acetate from the intermediate vinylchromium species does not appear to compete with carbon-carbon bond formation. In addition, the allylic acetate products have been shown to be useful allyl nucleophile precursors through palladium mediated reactions. These results suggest that acyloxyalkenyl bromides are efficient linchpins for multiple carbon-carbon bond formation.
