Abstract

Our computational and experimental studies show that the high order 1,n-zwitterionic intermediates (n = 5, 7 and 9) of allenoate-PR3 are real species. The cycloaddition reactions of these versatile intermediates with electrophilic-coupling partners provide novel and highly convergent synthetic approaches to medium- and large-ring compounds.
