- Photoredox-Catalyzed Decarboxylative Alkylation of Silyl Enol Ethers to Synthesize Functionalized Aryl Alkyl Ketones
-
Photoredox-catalyzed decarboxylative alkylation of silyl enol ethers has been developed. Diverse functionalized aryl alkyl ketones were afforded in modest to good yields using N-(acyloxy)phthalimide as an easy access alkyl radical source under mild and operationally simple conditions. The excellent performance of drug molecules such as fenbufen and indomethacin and naturally occurring carboxylic acids such as stearic acid and dehydrocholic acid further demonstrated the practicability of the reaction.

- Photoreactions of Benzonitrile with Cyclic Enol Ethers
-
Upon irradiation cyclic enol ethers such as 1-methoxy-cyclopentene (4) mainly add across the cyano group of benzonitrile (1) under formation of 2-azabutadienes of an imidoester type.This is in agreement with the so-called ΔG-correlation which was reported

- Nonacarbonyldiiron-, Pentacarbonyliron-, or Hexacarbonylmolybdenum-induced Reactions of 4,5-Polymethylene-substituted 2-Isoxazolines
-
The reaction of 4,5-polymethylene-substituted 2-isoxazolines, 3-phenyl-3a,5,6,7a-tetrahydro-4H-pyranoisoxazole or 3-phenyl-3a,4,5,6a-tetrahydrofuroisoxazole, with , , or resulted in the formation of 5-hydroxy-1-phenyl-1-pentanone or 4-hydroxy-1-phenyl-1-butanone, via the N-O and C-C bond cleavage of the 2-isoxazoline ring and the subsequent hydrolysis.The similar reaction of 7a-morpholino- and 7a-(1-pyrrolidinyl)-3-phenyl-3a,4,5,6,7,7a-hexahydro-1,2-benzoisoxazoles undergoes the N-O bond cleavage and, the subsequent elimination of the amino group or the C-3a-C-7a bond fission.Although the reaction of 6a-morpholino- and 6a-(1-pyrrolidinyl)-3-phenyl-3a,4,5,6a-tetrahydro-4H-cyclopentisoxazoles with undergoes the N-O bond cleavage, and the subsequent elimination of the amino group or the C-3a-C-6a bond fission, the reaction of those 2-isoxazolines with proceeds very slowly.The mechanisms are proposed for these reactions.
