Aldehydes and ketones, including acetophenone and benzophenone, are readily protected under mild, neutral conditions in the presence of various alcohols or orthoformates and catalytic amounts of indium(III) trifluoromethanesulfonate (0.8 mol %) under either room temperature or mild heating conditions to give the corresponding cyclic and acyclic acetals and ketals in good to excellent yields. Acid sensitive functional groups, N-Boc, THP, and TBDMS do not undergo competitive deprotection under the reported conditions.

The scope of asymmetric oxidation of sulfides using Fe(salan) complex as a catalyst and aqueous hydrogen peroxide as an oxidant in water was broadened by optimizing the reaction conditions with respect to reaction temperature, catalyst loading, and amount of water solvent. The oxidation proceeded with high enantioselectivity under the optimized conditions. The undesired over-oxidation of the resultant sulfoxides was significantly suppressed and the yields of sulfoxides were improved. Various functional groups were tolerant of the conditions.

The synthesis and biological testing of a series of sulfonyl phenols and sulfonyl aryl methyl ethers has revealed that p-methoxyphenyl p-toluenesulfonate is a very selective and effective antimalarial agent which shows pronounced activity against human skin cancer cells. Application of a counter-attack strategy permits the direct preparation of the requisite tosylate ether from the bis(tosylate) of dihydroquinone.
