Kuo, Ying Che published the artcileNew methods and reagents in organic synthesis. 26. Reductive desulfonylation of α-sulfonylacetates, Application In Synthesis of 1949-41-3, the publication is Chemical & Pharmaceutical Bulletin (1982), 30(8), 2787-92, database is CAplus.
α-Acyl-α-benzylsulfonyldiazomethanes RCOC(:N2)SO2CH2Ph (R = Ph, PhCH2CH2, Me2CH, cyclohexyl) have been converted to RCH(CO2H)SO2CH2Ph (I, same R) by Wolff rearrangement. Reductive removal of the benzylsulfonyl group of I (R = PhCH2CH2, Me2CH, cyclohexyl) can be achieved by Na-EtOH in THF. HO2CCRMeSO2CH2Ph (same R), prepared from benzyl α-benzylsulfonyl-α-substituted acetates, were also benzylsulfonylated under similar reductive conditions. The overall process, in combination with the Arndt-Eistert synthesis of α-sulfonylacetates from acyl chlorides and benzylsulfonyldiazomethane, provides a new, safe method for the homologation of carboxylic acids.
