, p. 654 - 663 (2007)
Copper ion catalyzed carbon-carbon bond forming reaction of N-acyliminium ions with diaryl malonates was achieved with high enantioselectivity. The key intermediates in the method were 2-methoxy-3,4-didehydropiperidines, which were easily prepared through
A facile synthesis of fluorinated 4-hydroxycoumarins
Li, Hui-Yin,Boswell, George A.
, p. 1551 - 1554 (2007/10/03)
Fluorinated 4-hydroxycoumarins were prepared from readily available fluorinated phenols via an AlCl3 catalyzed Friedel-Crafts ring closure and followed by sequential one pot decarboxylation and deacetylation with 90% H2SO4
