A Simple Method for the Selective Deprotection of p-Methoxybenzyl Ethers by Cerium(III) Chloride Heptahydrate and Sodium Iodide.

Page 5696, right column, line 7. The following sentence should have been added after the period: “The use of iodine in methanol is a simple and mild method for the selective deprotection of p-methoxybenzyl ethers. (Vaino, A. R.; Szarek, W. A. Synlett 1995, 1157-1158.)” We have inadvertently omitted this paper in our reference citations. JO0040238 10.1021/jo0040238 Published on Web 06/27/2000
