In the absence of any additional catalysts, the reactions of (CF3SO)2CH2, aldehydes, and 1,3-dienes gave gem-bis(triflyl)cyclohexenes in excellent yields with high regioselectivity. gem-Bis(triflyl)cyclohexene products can be easily converted to the corresponding aryl trifluoromethyl sulfones.

A hydrophilic amino-terminated poly(ethylene glycol)-type dual linker for solid phase synthesis of oleanolic acid derivatives using trityl chloride resin was designed and synthesized for the first time. Model reactions in both liquid and solid phase were performed to show the feasibility of its selective cleavage at two different sites. The biological assay results indicated that the long and flexible alkyl ether functionality in the linker is less likely to be critical for the binding event. Following the successful solid-phase synthesis of model compounds, the potential of this dual linker in reaction monitoring and target identification is deemed worthy of further study.
