Previously challenging pyridinyl cyclopentanes, cyclopentenes and bicyclo[2.1.1]hexanes with multiple substituents now can be efficiently prepared via a remote [3+2] cycloaddition reaction. The reaction features a simple diboron(4) catalyst, modular disconnection mode, broad scope, high atom economy and a unique dearomative/rearomative mechanistic process.
