A Practical Synthesis of Several Polyhydroxylated Chiral Building Blocks

A practical method for the synthesis of several useful polyhydroxylated chiral building blocks has been developed.The key reaction is the kinetic resolution of (E)-1-trimethylsilyl-4-alkoxy-1-buten-3-ol or (E)-1-trimethylsilyl-5-alkoxy-1-penten-3-ol using the Sharpless asymmetric epoxidation reaction.

Chiral Electrophilic Synthetic Building Blocks with Four Different Functional Groups from Tartaric Acid, 2,3- and 3,4-Epoxy-butanediol Derivatives in All Four Stereoisomeric Forms

Efficient and simple procedures have been developed for the preparation of the threo- and erythro-3,4-epoxy-1,2-butanediol derivatives 7 and 9 in both enantiomeric forms from tartaric acid.These epoxides should prove versatile as alkylating reagents in sy
