Cleavage of esters

The chemical inertness of the three-membered ring permitted many conversions of functional groups in diazirines. Esterifications, cleavage of esters and acetals, synthesis of acid chlorides, oxidation of hydroxy groups to carboxyl groups as well as Hofmann alkenation all left the three-membered ring intact (79AHC(24)63). [Pg.220]

The use of biocatalysts for the selective introduction and cleavage of esters is vast and has been extensively reviewed." Therefore only a few examples of the types of transformations that are encountered in this area of protective group chemistry will be illustrated to show some of the basic transformations that have appeared in the literature. The selective... [Pg.152]

The enzymatic cleavage of esters is a vast and extensively reviewed area of chemistry. Recently, several new esters have been examined primarily for the preparation of peptides and glycopeptides. [Pg.381]

TMSI also effects rapid cleavage of esters. The cleavage step involves iodide attack on the O-silylated ester. The first products formed are trimethylsilyl esters, but these are hydrolyzed rapidly on exposure to water.96... [Pg.240]
