Rh(III)-Catalyzed C-H Amidation of Indoles with Isocyanates.
The rhodium(III)-catalyzed direct amidation of indoles and pyrroles with aryl and alkyl isocyanates is described. These transformations provide a facile and efficient construction of C2-amidated N-heterocyclic scaffolds.
متن کاملPalladium(II)-catalyzed asymmetric hydrophosphination of enones: efficient access to chiral tertiary phosphines.
Chiral tertiary phosphines were synthesized by asymmetric hydrophosphination of aromatic enones catalyzed by an organopalladium complex with high yields and stereoselectivity. The procedure offers practical access to chiral tertiary phosphines.
متن کاملOrganocatalytic asymmetric hydrophosphination of nitroalkenes.
The use of a bifunctional Cinchona alkaloid catalyst has provided a new organocatalytic strategy for the enantioselective addition of diphenylphosphine to a range of nitroalkenes, affording optically active beta-nitrophosphines (up to 99% ee after crystallization); this organocatalytic approach, providing a direct route to a new class of potentially useful enantiopure P,N-ligands, constitutes a...
متن کاملZirconium-catalyzed intermolecular hydrophosphination using a chiral, air-stable primary phosphine.
Catalytic hydrophosphination of alkenes using a chiral, air-stable primary phosphine, (R)-[2'-methoxy(1,1'-binapthalen)-2-yl]phosphine, (R)-MeO-MOPH2, proceeds under mild conditions with a zirconium catalyst, [κ(5)-N,N,N,N,C-(Me3SiNCH2CH2)2NCH2CH2NSiMe2CH]Zr (1), to selectively furnish anti-Markovnikov, air-stable secondary phosphines or tertiary phosphines with slight modification of the proto...
متن کاملRh(III)-catalyzed directed C–H bond amidation of ferrocenes with isocyanates
[RhCp*(OAc)(2)(H(2)O)] [Cp* = pentamethylcyclopentadienyl] catalyzed the C-H bond amidation of ferrocenes possessing directing groups with isocyanates in the presence of 2 equiv/Rh of HBF(4)·OEt(2). A variety of disubstituted ferrocenes were prepared in high yields, or excellent diastereoselectivities.
