詳細

詳細

A highly versatile support for the solid phase immobilization of primary, secondary alcohols ^{[1,2,3,4,5,6,7,8,9,10,11]}, phenols ^[12], purines ^[13], and indoles ^[14]. Derivatization is effected by treating the support in DCM with an excess of alcohol in the presence of a catalytic amount of pyridinium p-toluenesulfonate. A similar DHP-based support has also been used for the immobilization of tetrazoles ^[15].Release of the product alcohol from the support has been carried out by treating with 95% TFA/5% water^[1] and TFA/DCM/EtOH ^[2,12]. However, the use of TFA can lead, in some cases, to trifluoroacetate formation. Methods which eliminate this potential side reaction include PPTS/BuOH/DCE ^[3], TosOH in DCM ^[16] and TosOH in DCE/BuOH ^[17].
