  名称：

  Ring-retentive deprotonation of cyclopropene-3-carboxamides

  摘要：

  A remarkable stability of anionic species generated from cyclopropene-3-carboxamides toward ring-opening is demonstrated. The resulting cyclopropenyllithium species can be reacted with a range of electrophiles, which allows for efficient introduction of additional substituents at C1 of the strained ring.
