ABSTRACT:
Carboxylate protective groups, a process for their preparation, their coupling to a funcitonal group, and their use
Carboxylates of polar, hydrophilic alcohols of the formula ##STR1## in which R is an unbranched or branched organic radical which contains, as polar members between aliphatic or araliphatic hydrocarbon bridges, ether oxygens, amine nitrogen groups or a mixture of ether and amine groups which can be incorporated into a cyclic structure, where the total length does not exceed 20 members and where, in the case of polyethylene glycol [(CH.sub.2 --CH.sub.2 --O).sub.n ], n indicates the number of the members and is defined as any integer, and
