Design and synthesis of benzoazepinone-derived cyclic malonamides and aminoamides as potent γ-secretase inhibitors
摘要:
We report the synthesis of benzoazepine-derived cyclic malonamides (2) and aminoamides (3) as gamma-secretase inhibitors for the potential treatment of Alzheimer's disease. The in vitro structure-activity relationships of 2 and 3 along with dog pharmacokinetic results are described. (C) 2007 Elsevier Ltd. All rights reserved.

Reactions of ω-halogenoalkylmalonicesters, X·[CH2]n·CH(CO2Et)2(X = Cl or Br; n= 2,3,4, or 5), with potassium t-butoxide in t-butyl alcohol and with sodium ethoxide in ethanol have been investigated. In both solvent systems and with each ester studied, the sole product is the cycloalkane-1,1-dicarboxylate which results from intramolecular nucleophilic substitution. In reactions with t-butoxide, the
