Oxime resins have been used for the synthesis of carboxylic acid derivatives by nucleolytic cleavage [1,2]. Carboxylic acids can be attached to the resin using DCC method. As the oxime linkage is not completely stable to TFA, the use of 25% TFA in DCM is recommended for removal of Boc groups. Caboxamides [3,4], esters [1,2], and enantiopure hydroxamic acids [5] have been synthesized with the resin and using hydrazine and amines, amino acid esters, and hydroxylamine, respectively, as cleavage agents. N-Methyloctadepsipeptides attached to the resin were cyclized by heating them in refuxing ethyl acetate for 2 days to give cyclodepsipeptide PF1022A analogues [6].
