Fe3+-Catalyzed transacetalization of 2-alkoxytetrahydrofurans with alcohols
摘要:
The transacetalization of 2-alkoxy-4-benzylidenctetraiiydrofurans with alcohols proceeds smoothly with the aid of Fe(ClO4)(3) catalyst. The catalyst reactivity is ordered as Fe(ClO4)(3)>Zn(ClO4)2>Mg(ClO4)(2). The present transacetalization provides an entry for various 2-alkoxytetrahydrofurans, which have potential as anticancer agents. (C) 2007 Elsevier Ltd. All rights reserved.
