Facile and selective deprotection of PMB ethers and esters using oxalyl chloride

Add time:09/07/2019    Source:sciencedirect.com

Oxalyl chloride, (0.5 equiv) was found to cleave the PMB group from alkyl, aryl PMB ethers, and esters to give corresponding alcohol and acid in good yields. This method offers simple and efficient protocol for the selective deprotection of PMB ether and ester in DCE at ambient temperature.
