Metal-free visible-light-promoted C(sp3)-H functionalization of aliphatic cyclic ethers using trace O2
Blackburn, Bryan G.,Cooke, Maria Victoria,Laulhé, Sébastien,Niu, Ben,Sachidanandan, Krishnakumar
supporting information, p. 9454 - 9459 (2021/12/09)
Presented is a light-promoted C-C bond forming reaction yielding sulfone and phosphate derivatives at room temperature in the absence of metals or photoredox catalyst. This transformation proceeds in neat conditions through an auto-oxidation mechanism which is maintained through the leaching of trace amounts of O2 as sole green oxidant. This journal is
Efficiency and Selectivity Aspects in the C-H Functionalization of Aliphatic Oxygen Heterocycles by Photocatalytic Hydrogen Atom Transfer
Raviola, Carlotta,Ravelli, Davide
supporting information, p. 803 - 809 (2019/04/25)
The C-H to C-C conversion in aliphatic oxygen heterocycles (dioxolanes, 1,3-dioxane, or cyclic carbonates) by photocatalytic hydrogen atom transfer and subsequent trapping of the resulting radical with phenyl vinyl sulfone was investigated. The performanc
Practical β-masked formylation and acetylation of electron-deficient olefins utilizing tetra(n-butyl)ammonium peroxydisulfate
Jung, Jae Chul,Kim, Yong Hae,Lee, Kieseung
experimental part, p. 4662 - 4664 (2011/09/30)
Various electron-deficient olefins reacted readily with 1,3-dioxolane or 2-methyl-1,3-dioxlane in the presence of TBAP to afford the corresponding 1,3-dioxolanylated or 2-methyl-1,3-dioxolanylated products in a complete regioselective manner in good to ex
Lipase-catalyzed resolution of stereogenic centers in steroid side chains by transesterification in organic solvents: The case of a 26- hydroxycholesterol
Ferraboschi, Patrizia,Rezaelahi, Shahrzad,Verza, Elisa,Santaniello, Enzo
, p. 2193 - 2196 (2007/10/03)
The Pseudomonas cepacia (PCL) lipase selectively catalyzes the acylation of the (25S)-isomer of the (25R,S)-26-hydroxycholesterol 1a when the transesterification is irreversibly carried out with vinyl acetate in a mixture of organic solvents (chloroform/t
Synthesis and reactivity of iron carbonyl complexes of β-silyl substituted α,β-unsaturated ketones
Gibson, Susan E.,Tustin, Gary J.
, p. 2427 - 2432 (2007/10/02)
β-Silyl α,β-unsaturated ketones, R3SiCH=CHC(O)Me (R3Si = Me3Si, ButMe2Si, PhMe2Si), react with at 35 deg C in diethyl ether to give tetracarbonyliron(0) complexes and at 55 deg C in toluene to give tricarbonyliron(0) complexes.Tricarbonyliron(0) and tricarbonyltMe2SiCH=CHC(O)Me>iron(0) react with methyllithium under a nitrogen atmosphere to give hexane-2,5-dione and 3-(tert-butyldimethylsilyl)hexane-2,5-dione, respectively, and with methyllithium under a carbon monoxide atmosphere to give the vinylketene complexes tricarbonyl(3-methyl-5-trimethylsilyl-1-oxa-1,2,4-triene)iron(0) and tricarbonyl(5-tert-butyldimethylsilyl-3-methyl-1-oxapenta-1,2,4-triene)iron(0) respectively.
Stereoselective Acetalization of 1,1- and 1,2-Disubstituted Diols as Common Principle in the Synthesis of the Enantiomers of the Bicyclic Acetal Pheromones endo- and exo-Brevicomin and Frontalin
Wershofen, Stefan,Classen, Arnold,Scharf, Hans-Dieter
, p. 9 - 18 (2007/10/02)
The acetalization of the 1,1- and 1,2-disubstituted diols 14-19 with the keto compounds 20 and 21 has been investigated.The substitution pattern of the used diols shows great influence on the stereochemistry of the obtained dioxolanes 22-27 (mixtures of d
