  Discovery of phenyl alanine derived ketoamides carrying benzoyl residues as novel calpain inhibitors

  摘要：

  Novel calpain inhibitors derived from phenyl alanine aldehydes or ketoamides carrying a benzoyl residue were prepared and evaluated for their biological potency. A brief structure-activity relationship elucidated the importance of ortho-substitutents in the benzoyl moiety. The most potent derivative, the ketoamide 19c, exhibited a K, of 6 nM and represents a novel class of reversible, highly potent and non-peptidic calpain inhibitors. (C) 2002 Elsevier Science Ltd.

  The first arylogous Michael reaction of 3-aryl phthalides has been developed. The reaction, promoted by catalytic amounts of KOH or K3PO4 and dibenzo-18-crown-6, affords the corresponding 3,3-disubstituted phthalides in good to high yields and as single diastereomers in nearly all studied cases.

  The [4 + 1] annulation of benzamides and aldehydes for phthalide synthesis was achieved via rhenium-catalyzed C–H activation, which demonstrates an unprecedented reaction pattern distinct from those of other transition-metal catalyses. The reaction also features readily available starting materials, a wide scope for both electro-rich and electro-deficient substrates, and the elimination of homoannulation

  苯甲酰胺和醛用于邻苯二甲酸酯合成的[4 +1]环化是通过rh催化的C–H活化而实现的，这证明了其与其他过渡金属催化剂截然不同的反应模式。该反应还具有容易获得的起始原料，对于富电和缺电的底物都有广泛的应用范围，并且消除了均环化副产物。

  A rhodium or palladium-catalyzed addition of boronic acids to phthalaldehydonitrile, followed by an intramolecular lactonization of cyano to access 3-substituted phthalides, is described. This procedure tolerates a series of functional groups, such as methoxy, fluoro, chloro, and vinyl groups. It is a novel procedure for the synthesis of 3-arylphthalides.
