Direct Access to α-Trifluoromethyl Enones via Efficient Copper-Catalyzed Trifluoromethylation of Meyer–Schuster Rearrangement
摘要:
A novel domino copper-catalyzed trifluoromethylated Meyer-Schuster rearrangement reaction with Togni's reagent was developed, leading to a-trifluormethyl (CF3) enone products with moderate to good yields. Furthermore, alpha-CF3 enones can be transformed toward important trifluoromethyl heterocyclic motifs in a one-pot version.
A simple base-mediated synthesis of diverse substituted ring-fluorinated 4H-pyrans (monofluorinated 4H-pyrans) from trifluoromethylated alkenes and 1,3-dicarbonyl compounds was developed.

This invention describes novel pyrazole compounds of formula IV:
1
wherein Ring D is a 5-7 membered monocyclic ring or 8-10 membered bicyclic ring selected from aryl, heteroaryl, heterocyclyl or carbocyclyl; R
x
and R
y
are independently selected from T-R
3
, or taken together with their intervening atoms to form a fused, unsaturated or partially unsaturated, 5-8 membered ring having 1-3 ring heteroatoms selected from oxygen, sulfur, or nitrogen; and R
2
, R
2′
, T, and R
3
are as described in the specification. The compounds are useful as protein kinase inhibitors, especially as inhibitors of aurora-2 and GSK-3, for treating diseases such as cancer, diabetes and Alzheimer's disease.
