We have developed a novel and highlyefficient, copper-catalyzed synthesis of internal alkynes via oxidative couplings of aromatic boronic acids with terminalalkynes at room temperature. The protocol uses inexpensive copper(I) oxide [Cu2O] as the catalyst, oxygen in the air as the stoichiometric oxidant; no ligand and sealed reaction vessels are required, and remarkable functional group tolerability
The present invention relates to inhibitors of aspartic proteinases, particularly, BACE. The present invention also relates to compositions thereof and methods therewith for inhibiting BACE activity in a mammal, and for treating Alzheimer's Disease and other BACE-mediated diseases.
The invention relates to pyrimidines and uses thereof, including to inhibit lysophosphatidic acid acyltransferase &bgr; (LPAAT-&bgr;) activity and/or proliferation of cells such as tumor-cells.
