Abstract: Herein, we have developed a method for the construction of spiro[benzofuran-2,2'-bicyclo[2.1.1]hexanes] via BF3·Et2O-catalyzed formal [2π + 2σ] cycloaddition of bicyclo[1.1.0]butanes with benzofuran-derived oxa(aza)dienes. This transformation allowed for facile access to... read more here.
