A mild method for the deprotection of tetrahydropyranyl (THP) ethers catalyzed by iron(III) tosylate
摘要:
A mild method for the deprotection of THP ethers catalyzed by iron(III) tosylate (2.0 mol %) in CH3OH has been developed. Iron(III) tosylate, Fe(OTs)(3)center dot 6H(2)O, is a commercially available solid that is inexpensive, noncorrosive, and easy to handle. The room temperature reaction conditions make this method attractive for deprotection of a range of THP ethers. (C) 2011 Elsevier Ltd. All rights reserved.
