As part of our continuing studies into the utility of allene groups, we report herein the preparation of the selective synthesis of (E)-α-ethynyl-α,β-unsaturated esters from allenyl acetates catalyzed by DABCO and their application to Sonogashira cross-coupling reaction (Scheme 1). First, various allenyl acetates were

• Phosphine-catalyzed intramolecular γ-umpolung addition of α-aminoalkylallenic esters: facile synthesis of 3-carbethoxy-2-alkyl-3-pyrrolines
  作者：Ian P. Andrews、Brian R. Blank、Ohyun Kwon

  DOI：10.1039/c2cc31347b

  日期：——

  An array of N-tosylated α-aminoalkylallenic esters was prepared and their cyclization under the influence of nucleophilic phosphine catalysts was explored. The α-aminoalkylallenic esters were prepared through aza-Baylis–Hillman reactions or novel DABCO-mediated decarboxylative rearrangements of allenylic carbamates. Conversion of these substrates to 3-carbethoxy-2-alkyl-3-pyrrolines was facilitated through Ph3P-catalyzed intramolecular γ-umpolung addition.

• Indium-Mediated Regio- and Chemoselective Synthesis of α-Hydroxyalkyl Allenic Esters and Gold-Catalyzed Cyclizations to Ethyl 2-Naphthoate Derivatives

  DOI：10.1021/ol801196g

  日期：2008.8.7

  The regio- and chemoselective synthetic method of functionalized alpha-hydroxyalkyl allenic esters was developed from the reactions of various aldehydes with organoindium reagent generated in situ from indium and ethyl 4-bromobutynoate. The alpha-hydroxyalkyl allenic esters possessing electron-donating groups were cyclized to ethyl 2-naphthoate derivatives through intramolecular C-alkylation catalyzed by gold salts.
