  Garratt–Braverman cyclization on basic alumina: a green protocol with improved selectivity

  摘要：

  A green protocol (compared to the existing methodology) for carrying out Garratt-Braverman cyclization has been developed. The method involves stirring a pre-absorbed bispropargyl sulfone/ether/sulfonamide over basic alumina. The reaction with sulfones was over within 10-15 mm at room temperature whereas for the ether/sulfonamide the reaction took 6-8 h at 130 degrees C. The products, aryl naphthalene derivatives, are obtained by simple filtration through Celite, in excellent yields. (C) 2014 Elsevier Ltd. All rights reserved.
