  Towards chemical libraries based on heterocyclic scaffolds with monofluorinated and difluoroalkyl side chains

  摘要：

  The preparation of focused chemical libraries, based on five- and six-membered heteroaromatic systems with mono- and gemdifluoroalkyl side chains, is described. Four heterocyclic scaffolds with a p-bromophenyl group have been easily prepared from readily available propargylic fluorides. Starting from these scaffolds, palladium-catalyzed reactions have been performed, including by automated procedures, to prepare libraries of molecules designed for biological applications.

  Flexible Synthesis of Pyrimidines with Chiral Monofluorinated and Difluoromethyl Side Chains

  摘要：

  Chiral pyrimidines with a fluorine atom in the benzylic position are easily accessible in high enantiomeric excesses from optically active propargylic intermediates by two complementary routes. Both the use of optically active propargylic fluorides and the fluorination of the chiral pyrimidine in the final stage give excellent results in terms of enantiocontrol. On the other hand, original pyrimidines with a difluoromethyl side chain are also obtained in a few steps from new propargylic ketones bearing a CHF2 substituent on the triple bond.

  Pyridinium 1,4‐zwitterionic thiolates as a class of sulfur‐containing synthons were applied to a [3+2] cascade cyclization reaction with activated alkynes, affording a library of polysubstituted thiophenes with excellent regioselectivities, especially those bearing multifarious fluorine‐containing groups.

  1,4-两性离子硫醇吡啶鎓盐作为一类含硫合成子被用于与活化炔烃的[3 + 2]级联环化反应，从而提供了具有良好区域选择性的多取代噻吩文库，尤其是那些带有多个含氟基团的噻吩。
