Arylcyclopropane yet in its infancy: the challenges and recent advances in its functionalization

Area of Science:

• Organic Chemistry
• Synthetic Chemistry

Background:

• Electronically unbiased arylcyclopropanes present significant synthetic challenges.
• Their reactivity is limited by the absence of pre-installed functional groups, unlike donor-acceptor cyclopropanes (DACs).
• Arylcyclopropane chemistry has progressed slowly due to these inherent difficulties.

Purpose of the Study:

• To review the historical development of electronically unbiased arylcyclopropane functionalization.
• To highlight current achievements, challenges, and opportunities in this field.
• To advocate for further research to advance arylcyclopropane chemistry.

Main Methods:

• Literature review of arylcyclopropane functionalization strategies.
• Analysis of reaction mechanisms and limitations.
• Discussion of synthetic advancements and future directions.

Main Results:

• Few strategies exist for the ring-opening of arylcyclopropanes.
• The field remains underdeveloped despite arylcyclopropanes being an early class of cyclopropanes.
• Significant potential exists for novel synthetic applications.

Conclusions:

• Electronically unbiased arylcyclopropanes are an under-explored area in organic synthesis.
• Overcoming activation challenges is crucial for their broader application.
• Concerted research efforts are needed to unlock the full potential of arylcyclopropanes.
