Zha, Gao-Feng;Fang, Wan-Yin;Leng, Jing;Qin, Hua-Li research published 《 A Simple, Mild and General Oxidation of Alcohols to Aldehydes or Ketones by SO2F2/K2CO3 Using DMSO as Solvent and Oxidant》, the research content is summarized as follows. A practical, general and mild oxidation of primary and secondary alcs. to carbonyl compounds proceeded in yields of up to 99% using SO2F2 as electrophile in DMSO as both the oxidant and the solvent at ambient temperature No moisture- and oxygen-free conditions were required. Stoichiometric amount of inexpensive K2CO3, which generated easy to sep. byproducts, was used as the base. Thus, 5-gm scale runs proceeded in nearly quant. yields by a simple filtration as the work-up. The use of a polar solvent such as DMSO, which usually promoted competing Pummerer rearrangement, was also noteworthy. This protocol was compatible with a variety of common N-, O- and S-functional groups on (hetero)arene, alkene and alkyne substrates. The protocol was applied (99% yield) to a formal synthesis of the important cholesterol-lowering drug Rosuvastatin.
