  A novel synthesis of 1,3,5-trisubstituted pyrazoles through a spiro-pyrazoline intermediate via a tandem 1,3-dipolar cycloaddition/elimination

  摘要：

  The syntheses of an important class of hitherto unreported 1,3,5-pyrazoles, inspired by all unanticipated eliminatory ring opening are described, The reported pyrazole compounds were constructed through the Huisgen cyclization of 2-methylene-1,3,3-trimethylindoline and an in situ generated nitrile imine. The newly formed spiro-pyrazoline intermediate presumably then undergoes a ring opening/elimination process to afford a pyrazole, as evidenced by single X-ray crystal data. The Current report constitutes the first formal observation of this kind of ring opening involving a spiro-pyrazoline intermediate. Published by Elsevier Ltd.
