Preparation of intermediates useful in the synthesis of antiviral nucleosides

The present invention is an efficient process for the manufacture of α-acyloxyacetaldehyde, a key intermediate in the synthesis of 1,3-oxathiolane and 1,3-dioxolane nucleosides.

A STUDY ON THE SYNTHESIS OF CARUMONAM STARTING FROM AN α-AMINO ACID

As part of a study on the synthesis of carumonam (1), a method starting from an α-amino acid was investigated.Cycloaddition of the mixed anhydride, derived from carbobenzoxyglycine (7) and isopropyl chloroformate, with the chiral imine (11b), derived from
