Aldol Reaction of Enol Acetates and Lactols with N-Chlorosuccinimide and Tin(II) Chloride. Diastereoselective Synthesis of Disubstituted Cyclic Ethers
Lactols reacted with enol acetates by a Lewis acid reagent, derived from N-chlorosuccinimide and tin(II) chloride, to produce 2-acetonyl cyclic ethers diastereoselectively.
