Synthesis of spiroheterocycles by palladium-catalyzed domino cycloisomerization/cross-coupling of α-allenols and Baylis-Hillman acetates

Alcaide, Benito,Almendros, Pedro,Del Campo, Teresa Martinez,Teresa Quiros

, p. 3344 - 3346 (2009)

A new domino hetero-cyclization/cross-coupling reaction of α-allenols and BH acetates that includes [(2,5-dihydrofuran-3-yl)methyl]acrylate derivatives, was prepared. The domino reaction provides a facile access to functionalized spiroindolinones, which p
