Racemic and enantiomerically pure alkynyl esters tethered, respectively, to 2-methyl-1,3-cycloalkanediones and 2-methylcycloalkanones were readily obtained starting from common intermediates, which were available on large scale. alkynyl ester - enantiomer-chain - elongation - trimethylsilylpropyne - Corey-Fuchs reaction
