Abstract

A chiral Lewis acid catalysed asymmetric [2+2] cycloaddition reaction of allenyl imide and alkenes was developed by Xiaohua Liu, Xiaoming Feng et al. in their Research Article (e202211596). This protocol provided a series of axially chiral cyclobutenes in high yields with excellent enantioselectivities. A stepwise mechanism was proposed based on experimental studies and DFT calculations, and π–π stacking interactions were identified as crucial for the enantioselectivity.
