International Classification:

G01N 1/30
C07D 453/04

US Classification:

435 405, 546134

Abstract:

Charged and neutral small fluorescent molecules based upon the styryl scaffold are useful as imaging agents for misfolded proteins such as amyloid plaque. Charged molecules are prepared using pyrrolidine catalyzed reactions by solution-phase synthesis. Neutral styryl molecules are prepared using acetic anhydride catalyzed reactions, Horner-Emmons reactions or Wittig reactions.
