Sequential rhodium/palladium catalysis: Enantioselective formation of dihydroquinolinones in the presence of achiral and chiral ligands

Compatible combinations of achiral and chiral ligands can be used in rhodium/palladium catalysis to achieve highly enantioselective domino reactions. The difference in rates of catalysis and minimal effects of ligand interference confer control in the domino sequence. The “all-in-one” 1,4-conjugate arylation and C~N cross-coupling through sequential Rh/Pd catalysis provides access to enantioenriched dihy-droquinolinone building blocks.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1310584-14-5, help many people in the next few years.Application In Synthesis of Palladium-Xphos

Enantioselective and Divergent Syntheses of Alstoscholarisines A, e and Their Enantiomers

Concise, enantioselective, and divergent syntheses of alstoscholarisines A and E are presented in 8 and 9 steps, respectively; alstoscholarisine E has never been accessed before. A boron-mediated aldol reaction and Rh-catalyzed cycloisomerization were exploited to access stereoisomers 8 and 9 as key intermediates. The challenging sterically congested alstoscholarisine core was furnished by a reductive transannular cyclization in the final steps. This strategy was also used for the syntheses of enantiomers of alstoscholarisines A and E.

The transition metal catalysed reactions of benzaldehydes and benzylideneamines with disilanes have been investigated. Palladium phosphine complexes catalyse the double silylation of the C=O bond in benzaldehydes and the C=N bond in benzylideneamines with 1,2-difluoro-1,1,2,2-tetramethyldisilane to yield alpha-(fluorodimethylsilyl)-alpha-(fluorodimethylsiloxy)toluene and N-methyl-N-(fluorodimethylsilyl)-alpha-(fluorodimethylsilyl)benzylamine respectively. When less activated disilanes such as 1,2-dichloro- and 1,2-dimethoxy-1,1,2,2-tetramethyldisilane were employed, the palladium phosphine complexes were less active and selective, resulting in extensive side reactions inclusive of 1,2-disiloxy-1,2-diphenylethane formation. The reaction of benzophenone with the difluorodisilane formed 2,2-dimethyl-4,4,5,5-tetraphenyl- 1,3-dioxa-2-silacyclopentane without affording the corresponding simple double silylation product. The formation of side products such as 1,2-disiloxy-1,2- diphenylethane in the reaction of benzaldehyde and 2,2-dimethyl-4,4,5,5- tetraphenyl-1,3-dioxa-2-silacyclopentane in the reaction of benzophenone appears to suggest intermediacy of radical and silylene species. Tris(dibenzylideneacetone)diplatinum-etpo (etpo = 4-ethyl-1-phospha-2,6,7- trioxabicyclo[2.2.2]octane catalyst system was more active for unactivated disilanes, catalysing double silylation of benzaldehydes with hexamethyldisilane. The same catalyst system was found to catalyse the ortho silylation of benzylideneamines with disilanes via intramolecular C-H activation; both mono- and bis-silylated products were obtained. Reaction rates and product distributions are rationalised in terms of the steric and electronic properties of the disilanes, substrates and the catalyst used. The Royal Society of Chemistry 2003.
