Bulky TBDPS and TIPS carboxylic esters were efficiently cleaved by a green and mild protocol using only DMF-H2O (20:1) at 70 degrees C. The neutral conditions tolerate various common acid- and base-labile functionalities, including alkyl and aryl silyl ethers. (C) 2015 Elsevier Ltd. All rights reserved.
