    • The self-condensation could be avoided by lowering concentration of the substrate (12 mM) and by trapping of enolate with the excessive base (3.3 equiv). The reverse addition of substrate to the base was also efficient. As a result, the yield of 8a increased to 82%. However, 2 could not be obtained from 6 by the improved procedure
