  Synthesis of 3-trialkylsilyl pyrazoles from β-oxo acylsilanes

  摘要：

  The synthesis of beta -oxo acylsilanes via cyclic sulfates is described and applied to carbohydrates. These compounds are used for the synthesis of new silylated pyrazoles linked to a carbohydrate moiety by the addition of hydrazines. The regiochemistry of the reaction was determined by NMR analyses (H-1/C-13 and H-1/N-15 correlations). (C) 2000 Elsevier Science Ltd. All rights reserved.
