Djurdjevic, Smilja,Leigh, David A.,McNab, Hamish,Parsons, Simon,Teobaldi, Gilberto,Zerbetto, Francesco
, p. 476 - 477 (2007)
Extremely high association constants (Ka's) of up to 2 × 107 M-1 in CH2Cl2 at room temperature are measured for chemically stable AAA-DDD and AA-DDD complexes which featurenovel and readily accessible multiple h
AAA-DDD triple hydrogen bond complexes
Blight, Barry A.,Camara-Campos, Amaya,Djurdjevic, Smilja,Kaller, Martin,Leigh, David A.,McMillan, Fiona M.,McNab, Hamish,Slawin, Alexandra M. Z.
, p. 14116 - 14122 (2009)
Experiment and theory both suggest that the AAA-DDD pattern of hydrogen bond acceptors (A) and donors (D) is the arrangement of three contiguous hydrogen bonding centers that results in the strongest association between two species. Murray and Zimmerman p
A Novel Convenient Synthesis of Pyridinyl and Quinolinyl Triflates and Tosylates via One-Pot Diazotization of Aminopyridines and Aminoquinolines in Solution

The first effective and simple method for the direct one-pot transformation of 2-, 3-, and 4-aminopyridines, 2,6-diaminopyridines, and 2-aminoquinoline into the corresponding pyridinyl and quinolinyl trifluoromethanesulfonates and tosylates in solvents was developed. The procedure involves diazotization of the heterocyclic amines with sodium nitrite in mixed hexane-DMSO or hexane-DMF solutions in the presence of trifluoromethanesulfonic acid or p-toluenesulfonic acid.
Synthesis of polyfunctional indoles and related heterocycles mediated by cesium and potassium bases

A general preparation of 2-substituted indoles starting from functionalized 2-alkynylanilines has been developed. This base mediated reaction has also been used to synthesize the heterocyclic core of the marine alkaloid hinckdentine A. Furthermore the reaction was successfully adapted to the solid phase. Benzofurans and isoindolones could also be prepared with this method.
