• Pd-Cu Bimetallic Catalyzed Domino Cyclization of α-Allenols Followed by a Coupling Reaction: New Sequence Leading to Functionalized Spirolactams
  作者：Benito Alcaide、Pedro Almendros、Raquel Rodríguez-Acebes

  DOI：10.1002/chem.200500228

  日期：2005.9.19

  A novel regioselective metal-catalyzed spirocyclization of alpha-allenols-cross coupling (Heck, Sonogashira, and Suzuki) reaction sequence, leading to potentially bioactive spirocyclic lactam derivatives has been developed. Precursors for the tandem spirocyclization-coupling reaction, alpha-allenols 2 a-d were obtained starting from alpha-oxolactams 1 a-c via indium-mediated Barbier-type carbonyl-allenylation

• An Alternative to Precious Metals: Hg(ClO₄)₂·3H₂O as a Cheap and Water-Tolerant Catalyst for the Cycloisomerization of Allenols
  作者：Benito Alcaide、Pedro Almendros、Amparo Luna、Elena Soriano

  日期：2015.7.17

  Hg(ClO4)(2)center dot 3H(2)O, a cheap, water-tolerant, and stable salt, catalyzes the cydoisomerization reaction or alpha-allenols to 2,5-dihydrofurans in an efficient and selective manner. The reaction is general and can be applied to differently functionalized substrates, including alkyl-substituted, aryl-substituted, enantiopure, and tertiary allenols. In addition, density functional theory (DFT) calculations were performed to obtain insight into various aspects of the controlled reactivity of a-allenols under mercury catalysis. They suggest a dual activation of the allenol by the Hg complex that drives the reaction to the chemoselective formation of 2,5-dihydrofurans.
• Efficient Entry to Diversely Functionalized Spirocyclic Oxindoles from Isatins through Carbonyl-Addition/Cyclization Reaction Sequences
  作者：Benito Alcaide、Pedro Almendros、Raquel Rodríguez-Acebes

  DOI：10.1021/jo0525027

  日期：2006.3.1

  A novel approach to diversely functionalized spirocyclic oxindoles has been developed by using different metal-mediated carbonyl-addition/cyclization reaction sequences. Spirocyclization precursors, 2-indolinonetethered homoallylic alcohols, (buta-1,3-dien-2-yl)methanols, and alpha-allenols have been obtained by regioselective addition of stabilized organoindium reagents to isatins in aqueous environment. Ruthenium-, silver-, and palladium-catalyzed reactions of the above unsaturated alcohol derivatives provided oxaspiro oxindoles.
