一般描述
Rink acid resin is a super acid-labile support for the solid phase immobilization of carboxylic acids [1]. Cleavage can be effected with as little as 10% AcOH in DCM, providing highly acid-sensitive products in high yields and purities. However, care must be taken to prevent product loss during synthetic manipulations [2], owing to the extreme acid sensitivity of this support.
Treatment with HCl in THF [3] or Ph3PCl2[4] has been shown to efficiently convert this resin to the corresponding benzhydryl chloride, to which can be coupled a wide range of functional groups: hydroxylamines [3], alcohols, amines, acids and thiols [4].
Rink acid resin has also been converted to a trifluoroacetate with TFA and used in a similar manner to immobilize amines, thiols, alcohols, and phenols [5]. In a more detailed study, the same authors found 1 M trifluoroacetic anhydride in 2,6-lutidine to give superior results with less degradation of the linker [6, 7]. Rink resin trifluoroacetate has also been used to prepare purines [8, 9].
Cleavage of amines and alcohols from this support has been carried out with either 5% TFA in DCM [4] or 20% TFA in DCM [5]; thiols were released with either 5% TFA in DCM [4] or 95% aq. TFA [5].
