The Use of Tin (IV) Chloride to Selectively Cleave Benzyl Esters over Benzyl Ethers and Benzyl Amines
(Canadian Journal of Chemistry, 2014)
Benzyl esters are cleaved upon reaction with SnCl4, resulting in isolation of the corresponding carboxylic acid. Importantly, benzyl ethers, amines and amides do not undergo debenzylation under these conditions, nor do a ...
Synthesis of symmetric meso-H dipyrrin hydrobromides from 2-formyl pyrroles
The reaction of 2-formyl pyrroles in acidic methanol gives the corresponding symmetric, meso-H 4,6-dipyrrin hydrobromides. This convenient strategy involves initial deformylation under the acidic conditions, followed by ...
