Protective Groups In Organic Synthesis. To a limited extent, carboxylic acids have been protected as amides or hydrazides, derivatives that complement esters in methods used for their cleavage. Some esters that have been used as protective groups are included in Reactivity Chart 6 (Chapter 10). A protecting group is introduced into a molecule by chemical modification of a functional group to obtain chemoselectivity in a subsequent chemical reaction and is an important role in organic synthesis. Protecting Groups for organic synthesis - Format: PDF. Protecting Groups A valuable addition to the synthetic chemist's bookshelf. The focus is on a relatively small number of commonly used protecting groups, on deprotecting conditions, and on the extensive use of schemes to aid visual retrieval of information.
