  Complementary α-alkylation approaches for a sterically hindered spiro[pyrazolopyranpiperidine]ketone

  摘要：

  Complementary alpha-alkylation methods are used to derivatize a sterically hindered spiro[pyrazolopyranpiperidine]ketone. More specifically, enolate alkylations in the presence of DMPU and aldol condensations are employed to deliver these compounds. (C) 2012 Elsevier Ltd. All rights reserved.
