  Versatile Synthesis of Dissymmetric Diarylideneacetones via a Palladium-Catalyzed­ Coupling–Isomerization Reaction

  摘要：

  As a twofold Michael system, the diarylideneacetone core is of particular interest in organic synthesis and for therapeutic applications. To overcome the drawbacks of the classical Claisen-Schmidt protocol, a new methodology for the synthesis of dissymmetric (hetero)diarylideneacetones has been developed. Conditions were optimized with a Box-Behnken design of experiment. The milder reaction conditions allow the efficient preparation of fluorinated, or heteroaromatic, dissymmetric diarylideneacetones which cannot be obtained through the classical Claisen-Schmidt protocol.

• Synthesis and Structure−Affinity Relationships of Novel Dibenzylideneacetone Derivatives as Probes for β-Amyloid Plaques

  A new and extensive set of dibenzylideneacetone derivatives was synthesized and screened for affinity toward A beta(1-42) aggregates. Structure-activity relationships revealed the binding of dibenzylideneacetones to be affected by various substituents. The introduction of a substituent group in the ortho position reduced or abolished the binding. However, the para position was highly tolerant of sterically demanding substitutions. Three radioiodinated ligands (6, 70, and 71) and two F-18 fluoro-pegylated (FPEG) ligands (83 and 85) were prepared, all of which displayed high affinity folr A beta(1-42) aggregates (K-i ranging from 0.9 to 7.0 nM). In biodistribution experiments, they exhibited good initial penetration (1.59, 4.68, 4.56, 4.13, and 5.15% ID/g, respectively, at 2 min) of and fast clearance from the brain. Autoradiography with sections of postmortem AD brain and transgenic mouse brain confirmed the high affinity of these tracers. These preliminary results strongly suggest the dibenzylideneacetone structure to be a potential new scaffold for beta-amyloid imaging probes.
