Abstract: Water is an ideal solvent for chemical transformations in environmentally friendly and sustainable processes. An operationally simple, metal-free, and green approach to the synthesis of oxindole-fused spirotetrahydrofurans from 3-allyl-3-hydroxy-2-oxindoles in water is described. This method… read more here.
