𝘕,𝘕'-Diisopropyl-𝙊-𝙩𝙚𝙧𝙩-butyl isourea: an efficient reagent for 𝙩𝙚𝙧𝙩-butyl esters synthesis

tert-Butyl esters are commonly used as protecting group of carboxylic acids in multi-step synthesis, especially with amino acids, peptides and natural products. [1] The importance of this relatively hindered protecting group is well established.
