Soluble polymer-supported organic synthesis.
Soluble polymers have been used as supports for reagent/catalyst immobilization and synthesis. Two polymers are commonly used in this context, linear polystyrene and poly(ethylene glycol). The complementary solubility properties of these polymers allow access to a wide range of chemistries. Parallel and combinatorial libraries of small molecules have been prepared using these polymers, and reag...
متن کاملSoluble polymer-supported convergent parallel library synthesis.
Soluble polymer-supported convergent synthesis has for the first time been successfully exploited for parallel library synthesis; sub-libraries of tripeptide iodoarenes and arylboronic acids reacted smoothly in a multipolymer PdII-catalyzed Suzuki coupling reaction to generate a library of bisaryl-linked hexapeptides.
متن کاملStereoselective Synthesis of α-Amino-C-phosphinic Acids and Derivatives.
α-Amino-C-phosphinic acids and derivatives are an important group of compounds of synthetic and medicinal interest and particular attention has been dedicated to their stereoselective synthesis in recent years. Among these, phosphinic pseudopeptides have acquired pharmacological importance in influencing physiologic and pathologic processes, primarily acting as inhibitors for proteolytic enzyme...
متن کاملBi(OTf)3-catalyzed three-component synthesis of α-amino acid derivatives.
A highly efficient Bi(OTf)3-catalyzed multicomponent synthesis of arylglycines from readily available starting materials is described. The reaction proceeds under mild conditions and provides a general route to various N-protected arylglycines.
متن کاملBismuth- and Iron-Catalyzed Three-Component Synthesis of α-Amino Acid Derivatives: A Simple and Convenient Route to α-Arylglycines
Efficient bismuthand iron-catalyzed three-component syntheses of α-arylglycines have been developed. These methods provide a general, atom-economic route to various N-protected α-arylglycines starting from readily available amides (or carbamates), glyoxalates, and (hetero)arenes with water as the only by-product. Scope and limitations of bismuthand iron-catalyzed reactions are discussed and com...
