Chiral orthoesters in organic synthesis: Novel reagents for the enantioselective acylation of silylenolethers

Dialkyl trans-2-alkoxy-2-alkyl-1,3-dioxolan-4,5-dicarboxylates and the corresponding N,N,N,N-tetramethyl-4,5-diamides have been prepared respectively from dialkyl tartrates or tartaric acid diamides. They smoothly reacted with silylenolethers in the prese

Novel Enantioselective Acylating Agents. The Reactions of Chiral Ortho Esters and Silylenol Ethers as a Route to Optically Active Monoprotected 1,3-Dicarbonyl Compounds

A novel enantioselective route to monoprotected 2-substituted-1,3-dicarbonyl compounds has been developed via acylation of silylenol ethers with chiral ortho esters derived from diethyl or di-isopropyl (R,R)-tartrates; good yields and stereoselectivity ca
