  A Divergent Approach to the Synthesis of 3-Substituted-2-pyrazolines: Suzuki Cross-Coupling of 3-Sulfonyloxy-2-pyrazolines

  摘要：

  The efficient Suzuki cross-coupling of pyrazoline nonaflates with organoboron reagents was achieved to afford diverse 3-substituted-2-pyrazolines in excellent yield. The nonaflates displayed improved reactivity over the corresponding triflates and smoothly coupled to a variety of aryl- and heteroarylboronic acids. This process and its broad scope constitute a rapid, divergent strategy for the synthesis of elaborated 2-pyrazolines that are not readily obtained via conventional methods.
