Copper-Catalyzed Chemoselective Cyclization Reaction of 2-Isocyanoacetophenone: Synthesis of 4-Hydroxyquinoline Compounds

A copper-catalyzed intramolecular cyclization reaction of 2-isocyanoacetophenone derivatives to afford 4-hydroxyquinolines chemoselectively is described. The transformation proceeds through enol tautomerism and a subsequent C-C bond formation. Compared to previous methods, this study provides a new protocol for the construction of 4-hydroxyquinoline compounds from functionalized isocyanides under mild conditions.

The Reaction of o-Aminoacetophenone N-Tosylhydrazone and CO2 toward 1,4-Dihydro-2H-3,1-benzoxazin-2-ones

A transition-metal-free reaction of o-aminoacetophenone N-tosylhydrazone and CO2 has been developed, leading to a series of 1,4-dihydro-2H-3,1-benzoxazin-2-ones in moderate to good yields. This procedure proceeds with the sequential fixation of CO2 by amino leading to carbamic acid and the intra- molecular insertion of hydroxyl to carbene. (Figure presented.).

Chemoselective Alkylation of Aminoacetophenones with Alcohols by Using a Palladacycle-Phosphine Catalyst

The development of efficient and environmentally benign palladacycle-phosphine catalyzed process to enable the formation of chemoselective C-alkylated or N-alkylated aminoacetophenones with alcohols is described. This methodology proved to be tunable by variation of the base and the temperature, which allows for the isolation of structurally diverse C-alkylated and N-alkylated aminoacetophenones. Moreover, this methodology has been applied to the synthesis of biologically and industrially important donepezil.

Catalyst-free geminal aminofluorination of ortho-sulfonamide-tethered alkylidenecyclopropanes via a Wagner-Meerwein rearrangement

A catalyst-free intramolecular geminal aminofluorination of ortho-sulfonamide-tethered alkylidenecyclopropanes has been developed. The reaction proceeded through two SET processes with Selectfluor to give a fluorinated cyclopropylcarbinyl cation and a further Wagner-Meerwein rearrangement to generate a cyclobutyl carbocation, which undergoes intramolecular nucleophilic capture by amide to forge fluorinated cyclobuta[b]indoline derivatives. A polycyclic multi-fluorinated byproduct was also formed through a Ritter-type reaction in some cases.

Metal-free intramolecular oxidative decarboxylative amination of primary α-amino acids with product selectivity

A novel metal-free intramolecular oxidative decarboxylative coupling of primary α-amino acids with 2-aminobenzoketones under mild and neutral conditions was developed. Different quinazolines can be selectively obtained by various oxidants.

Iron-catalyzed, directed oxidative arylation of olefins with organozinc and grignard reagents
