Versatile Pd(II)-Catalyzed C−H Activation/Aryl−Aryl Coupling of Benzoic and Phenyl Acetic Acids
摘要:
The use of aryltrifluoroborates as coupling partners and O-2 as the oxidant substantially improves the scope and practicality of the Pd-catalyzed C-H activation/C-C coupling reaction. The newly discovered protocol made possible, for the first time, the orthocoupling of electron-deficient arenes and phenyl acetic acids With organometallic reagents.
The present invention provides terphenyl guanidine compounds of formula I
The present invention also provides methods for the use thereof to inhibit β-secretase (BACE) and treat β-amyloid deposits and neurofibrillary tangles.
