Pd-catalyzed enantiodivergent and regiospecific phospha-michael addition of diphenylphosphine to 4-oxo-enamides : efficient access to chiral phosphinocarboxamides and their analogues
The palladacycle-catalyzed asymmetric P-H addition of 4-oxo-enamides has been developed, which provides efficient access to phosphinocarboxamides and their analogues. Solvent-mediated reversal of stereoselectivity (ee from ...
Enantioselective addition of diphenylphosphine to 3-methyl-4-nitro-5-alkenylisoxazoles
An enantioselective Michael addition reaction of diphenylphosphine to substituted alkenylisoxazoles has been developed. The reaction proceeds efficiently under mild conditions with high yields (up to 99%) and moderate to ...
Palladacycle catalyzed asymmetric P-H addition of diarylphosphines to N-enoyl phthalimides
The first asymmetric phospha-Michael addition of diarylphosphines to N-enoyl phthalimides has been developed in the presence of a chiral palladacycle catalyst. A library of free chiral tertiary phosphine adducts were ...
