The cyclodimerization reaction of N-substituted-5-hydroxy-pyrrolydinones promoted by BF3 center dot Et2O and HCl to obtain symmetrical 1,4-dioxane derivatives was achieved in moderate to good yields, mild conditions, and short reaction times. These transformations render a promising alternative route that provides access to diverse 1,4-dioxane derivatives with a wide structural diversity. (C) 2015 Elsevier Ltd. All rights reserved. (AU)
