Synthesis of novel pyrazole-linked norcantharidin derivatives of substituted aromatic amines with efficient 1,3-dipolar cycloaddition

摘要

Highly efficient, practical and convient synthesis of fifteen compounds by the [3+2] 1,3-dipolar cycloaddition reaction of norcantharidin derivatives of substituted aromatic amines with three hydrazines in the presence of Chloramine-T.
