Unconventional ionic ring-deconstruction pathways of a three-membered heterocycle†
Abstract
Two different ionic deconstructions of a three-membered COP ring have been discovered. The first involves displacement of the CO unit (aldehyde elimination) induced by base whilst the second involves acid-initiated extrusion of the ring-carbon (2-methyl-2-butene). Insight into the latter deconstruction was obtained by quantum chemical calculations.
