A convenient and practical strategy for the cross-coupling of N-Boc protected piperazines with aryl iodides in the presence of the catalytic system CuBr/rac-BINOL is developed.
We report a novel method for micropatterning of active proteins on anti-fouling surfaces via spatially well-defined and dense binary poly(ethylene glycol)s (PEGs) brushes with controllable… (More)
Abstract A siloxy- l -serine organocatalyst has been developed to catalyze the asymmetric three-component Mannich reactions in the presence of water via a biphasic system, furnishing the Mannich… (More)
A simple protocol is developed for the cross-coupling of nitrogen-containing heterocycles and aryl halides in water using Cu2O and Bu4NBr as the catalysts.
A simple and practical protocol for the cross-coupling of methanesulfonamide and aryl iodides under ligand-free copper(I)-oxide-catalyzed conditions in water is reported. The method allows the… (More)
Under optimized conditions, a wide variety of N-arylated benzamides (III) and (V) is obtained in good yields, in general.
Abstract A siloxy- l -serine organocatalyst has been developed to catalyze direct asymmetric aldol reactions in the presence of water, furnishing the β-hydroxy carbonyl scaffold in high enantio- and… (More)
