Lewis acid-mediated mono- and bis-addition of C -nucleophiles to 1,3-dioxolan-4-ones
摘要:
The reactions of 1,3-dioxolan-4-ones, readily available from a-hydroxy acids and aldehydes, with C-nucleophiles are described. Two possible reaction pathways resulting in O-substituted acids and tri-(hetero)arylmethanes are shown. (C) 2018 Elsevier Ltd. All rights reserved.

An efficient method for the synthesis of O-substituted mandelic acidscontaining alkenyl, alkynyl, methoxycarbonyl, or phenacyl fragments via the Lewis acid-catalyzed reaction of 1,3-dioxolan-4-ones with different C-nucleophiles is proposed.
