DABCO-catalyzed formation of 4-methoxy-1,3-dioxolan-2-ones and their synthetic applications in the aromatic electrophilic substitution
摘要:
DABCO is a very effective catalyst in the formation of 4-methoxy-1,3-dioxolan-2-ones 10 from the corresponding alpha-carbonatoaldehydes 8 intermediates. The Friedel-Crafts reaction pathway of the cyclic carbonate 10 is dependent on the electron density of the aromatic nucleophiles. (C) 2008 Elsevier Ltd. All rights reserved.
