Investigation of the origins of regiochemical control in [4+2] cycloadditions of 2-pyrones and alkynylboronates

The [4+2] cycloaddition of 2-pyrones with substituted alkynylboronates has been studied. In general, the highest yielding cycloadditions were obtained in reactions that employed a trimethylsilyl-substituted alkynylboronate. The highest regioselectivities were obtained using the corresponding phenyl-substituted alkyne, which provided a single regioisomer irrespective of the 2-pyrone used. Mechanistic studies suggest that the high regioselectivity observed is due to stabilization of a zwitterionic transition state. Georg Thieme Verlag Stuttgart · New York.
