Abstract: Abstract A novel domino intramolecular [3+2] cycloaddtion and ring-opening aromatization process has been successfully developed for the efficient direct synthesis of pyrrolyl or indolyl substituted 9,10-dihydrophenanthren-9-ol analogues. And 1-(phenanthren-9-yl)-1H-pyrroles can be easily obtained via dehydration… read more here.

Abstract: The unique reactivity of indolyl-substituted p-QMs as a new type of two-carbon synthon has been explored for the first time in a novel iron(III)-catalyzed tandem annulation. This (2+2) annulation/retro-4π electrocyclization/imino-Nazarov cyclization cascade reaction is characterized… read more here.
