  Solvent-free desymmetrisation of a meso-dialdehyde with chiral alcohols, led to preparation of 4-silyloxy-6-alkyloxytetrahydro-2H-pyran-2-one derivatives with a 96% de. This methodology, which yields the corresponding methyl nor-mevaldates with 99% ee, has been applied to the enantioselective synthesis of the (−)-(R) and (+)-(S) nor-mevalonic acid lactones.
