Carboxyl groups, protection cleavage

Cathodic 1,2-elimination of activated esters leads to the cleavage of the C—O bond and this method is useful for the deprotection of protected carboxyl groups (Scheme 9) [22, 23],... [Pg.203]

Protection of carboxyl groups. Phenacyl esters can be cleaved in 90% yield with Zn-HOAc/DMI. For peptides that are poorly soluble in DMF, cleavage can be effected with Zn-anthranilic acid-pyridine in a mixture of N-methylpyrrolidone and DM.SO (86-92% yield). [Pg.381]
