Alkylboron Cross-Coupling Reactions
The ability to append alkyl moieties onto preexisting molecular scaffolds is of significant interest owing to the breadth of the diversified compounds that can be accessed in late stage synthesis. There are a number of procedures that are capable of incorporating alkyl subunits into organic molecules; however, many of these strategies are limited in scope. In particular, the highly reactive nat...
متن کاملSuzuki-Miyaura cross-coupling reaction catalyzed using highly efficient CN-dimeric ortho-palladated complex under microwave irradiation and conventional heating
Suzuki cross-coupling reaction of different aryl halides with arylboronic acids was successfully carried out in methanol using ortho-palladated complex of 2-methoxyphenethylamine. All substrates afforded the corresponding products in good to high yields in the presence of low amounts of this complex as efficient and active catalyst. Application of microwave irradiation improved the yields of th...

متن کاملIron-catalyzed cross-coupling reactions.
Simple iron salts such as FeCl(n), Fe(acac)(n) (n = 2,3) or the salen complex 4 turned out to be highly efficient, cheap, toxicologically benign, and environmentally friendly precatalysts for a host of cross-coupling reactions of alkyl or aryl Grignard reagents, zincates, or organomanganese species with aryl and heteroaryl chlorides, triflates, and even tosylates. An "inorganic Grignard reagent...
متن کاملHeat-accelerated degradation of solid-state andrographolide.
The stability of andrographolide, the major active diterpene lactone from Andrographis paniculata (BURM. f.) WALL. ex NEES., was determined to show that, while crystalline andrographolide was highly stable even at 70 degrees C (75% relative humidity) over a period of 3 months, its amorphous phase degraded promptly. Heat-accelerated conditions revealed second-order kinetics of the decomposition ...
