A novel protocol for the efficient preparation of α-hydroxy allylic thioesters via a Lewis base-catalyzed tandem isomerization/allylic alkylation process is reported. The resulting allylic thioesters can serve as valuable scaffolds to undergo a stereosele

The Pummerer reaction of acetic anhydride with both alkyl aryl sulfoxides and dialkyl sulfoxides was efficiently promoted by a mesoporous aluminosilicate Al-MCM-41 to afford the corresponding α-acetoxy sulfides in high yields. The catalyst was easily reco

The first highly enantioselective organocatalytic rearrangement of α-acyloxy-β-keto sulfides to α-acyloxy thioesters has been developed which provides a number of important synthetic building blocks in high yield and with excellent enantioselectivities (e
