A sequential C−H/C−C functionalization strategy was reported to effect the otherwise challenging synthesis of 1,3-disubstituted cyclobutane building blocks. Numerous aryl, heteroaryl, alkenyl, and alkynyl groups can be installed at the 3-position of the cyclobutanering with exclusive cis-selectivity.
